ACS Citation Examples

See complete ACS references beside the pattern that creates them. Start with the source type—not the fact that you opened it online—then compare every author, title, date, locator, and identifier with the original record.

How to use these ACS citation examples

A good ACS citation example is a model, not a block of text to copy unchanged. First identify what you actually used: a journal article, an entire book, one chapter, a specific webpage, a preprint, a dataset, or another source. Then match the visible metadata to the labeled pattern. A PDF downloaded from a website can still be a journal article; a report viewed in a browser remains a report. The intellectual form of the work determines the format.

Next, verify the values against the primary record. Keep authors in publication order, reproduce the full title accurately, and use the journal title or accepted abbreviation requested by your target publication. Include volume, issue, pages, article number, DOI, URL, and access date only where the source type and your instructions call for them. An elegant example cannot compensate for a misspelled author or a DOI belonging to another paper.

Finally, connect each full reference to the marker in your text. Many current ACS journals use consecutively numbered references and unparenthesized superscript citations. Courses and books can specify another ACS treatment. The reference patterns below focus on the full entries; the in-text section explains the short markers that point to them.

Source-by-source

Complete ACS reference examples

Each card separates the reusable pattern from one finished reference. Supported sources link directly to a generator with the correct form ready to use.

01
Journal article

ACS journal article citation example

ACS / PATTERN

Author(s). Article title. Journal Title Year, Volume (Issue), pages or article number. DOI: identifier

Tan, G. Y.; Das, M.; Keum, H.; Bellotti, P.; Daniliuc, C.; Glorius, F. Photochemical single-step synthesis of β-amino acid derivatives from alkenes and (hetero)arenes. Nat. Chem. 2022, 14 (10), 1174−1184. DOI: 10.1038/s41557-022-01008-w

Preserve author order and include the article title. A standard journal abbreviation may be required; verify it rather than inventing one. Use either an inclusive page range or the published article number, then add the article DOI when available.

02
Whole book

ACS book citation example

ACS / PATTERN

Author(s). Book Title, edition; Publisher: Place, Year. DOI: identifier

Atkins, P. Concepts in Physical Chemistry, 2nd ed.; Royal Society of Chemistry, 2024. DOI: 10.1039/9781837674244

Cite a whole book when the argument or information comes from the work as a whole. Include an edition after the title when it is not the first. Publisher location policies vary across versions and destinations, so follow the pattern required for your submission.

03
Website

ACS website citation example

ACS / PATTERN

Author or organization. Page title. Website name. Publication date. URL (accessed date).

American Chemical Society. ACS Publications Home Page. https://pubs.acs.org/

Use the individual page rather than a search-result URL. A responsible organization can serve as author when no person is credited. Do not turn a footer copyright year into a publication date or add an access date unless the applicable guidance requests one.

Open generator
04
Book chapter

ACS chapter in an edited book example

ACS / PATTERN

Chapter author(s). Chapter title. In Book Title; Editor(s), Eds.; Publisher: Place, Year; pp pages.

Chapter Author, A. A. Chapter title. In Book Title; Editor, E. E., Ed.; Publisher: Place, 2026; pp 20−38.

A chapter reference begins with the chapter author and title, not the book editor. The word “In” introduces the containing book. Add editors, publisher details, year, and the chapter page span required by the source and your instructions.

05
Preprint

ACS preprint citation example

ACS / PATTERN

Author(s). Title. Repository, date. DOI or URL (accessed date).

Author, A. A.; Author, B. B. Title of Preprint. ChemRxiv, 2026. DOI: 10.26434/chemrxiv-00000

Label the repository and keep the preprint identifier. If a peer-reviewed version now exists and is the work you used, cite that version instead. Never describe a preprint as a published journal article simply because it has a DOI.

06
Dataset

ACS dataset citation example

ACS / PATTERN

Creator(s). Dataset Title; Repository, Year. DOI or stable URL.

Research Group. Spectroscopic Data for Catalyst Screening; Data Repository, 2026. DOI: 10.1234/example.dataset

Identify the dataset itself, not only the article that discusses it. Include the creator, dataset title, repository, year, version when relevant, and a persistent identifier. This illustrative record shows field placement and must be replaced with real metadata.

07
Numbered list

ACS bibliography example with mixed sources

ACS / PATTERN

1. First source cited. 2. Next new source cited. 3. Next new source cited.

1. Tan, G. Y.; Das, M.; et al. Photochemical single-step synthesis of β-amino acid derivatives from alkenes and (hetero)arenes. Nat. Chem. 2022, 14 (10), 1174−1184. DOI: 10.1038/s41557-022-01008-w 2. Atkins, P. Concepts in Physical Chemistry, 2nd ed.; Royal Society of Chemistry, 2024. DOI: 10.1039/9781837674244 3. American Chemical Society. ACS Publications Home Page. https://pubs.acs.org/

A numerical reference list follows first citation order rather than source type or alphabet. When a source appears again in the paper, point back to its existing number instead of adding the same entry twice.

ACS in-text citation examples

The short marker must match one full entry. Pick the treatment required by your publication or course and use it consistently throughout the document.

Generate an ACS in-text citation
01Superscript number
Catalytic activity increased under visible light.¹–³

Common in current ACS journals. Numbers are assigned by first mention and a repeated source keeps the same number.

02Number in parentheses
Catalytic activity increased under visible light (1–3).

Use italic parenthetical numbers only when the governing instructions request this treatment.

03Author–date
Catalytic activity increased under visible light (Tan et al., 2022).

Use this variant with a compatible author–date reference list, not as an isolated change to one citation.

Final review

Six checks before you submit

Generated formatting is only one layer of accuracy. Compare the finished document with the source records and the instructions for your actual destination.

Read the current ACS Style Quick Guide
01

Source type

Format the work you used, not the browser, database, or PDF viewer that delivered it.

02

Author order

Keep contributors in the order printed by the source and preserve group authors when appropriate.

03

Title and container

Distinguish the article or chapter title from the journal, book, repository, or website containing it.

04

Publication details

Verify year, volume, issue, page span, article number, edition, publisher, and date from a primary record.

05

Persistent identifier

Use the DOI belonging to the cited work or a stable direct URL; remove unnecessary tracking parameters.

06

Citation order

Match every in-text number to one full entry and keep the numerical list in order of first appearance.

Examples FAQ

Questions about ACS citation examples

01What does a complete ACS citation look like?

Its exact fields depend on the source. A journal article normally includes authors, article title, journal title, year, volume, issue when applicable, pages or article number, and DOI. Books and websites follow different patterns.

02Can I copy an ACS example and replace the words?

Use the example as a field-order guide, but verify the rules for your source type. Replacing text mechanically can leave an article with book punctuation or a webpage with invented publication details.

03Should an ACS reference include an article title?

Current ACS guidance and journal instructions commonly include article titles. Follow the exact author instructions for the journal or course receiving your work.

04Are ACS references alphabetical or numbered?

The common numerical system orders references by their first appearance in the text. An author–date variant can use a different list arrangement, so do not combine the two systems.

05Do all online sources use the website format?

No. A journal article, book, dataset, report, or preprint keeps that source type when accessed online. Use the website pattern for content that is genuinely a webpage.

06Where can I generate the examples automatically?

CiteLab currently provides dedicated journal article, book, website, bibliography, and in-text citation tools. Unsupported examples are shown as transparent patterns rather than pretending the tool can format every source automatically.
