Mastering ACS Citation Style: A Comprehensive Guide

By ACS Citation Team

The American Chemical Society (ACS) citation style is widely used in chemistry and related scientific disciplines. This comprehensive guide will help you understand how to properly format your citations and references in ACS style.

Understanding ACS Citation Style

ACS style follows specific guidelines for in-text citations and the references list. Here's what you need to know:

In-Text Citations

In ACS style, in-text citations are superscript numbers that correspond to references in the bibliography. They should be:

  • Placed after punctuation marks
  • In order of appearance in the text
  • Used consistently throughout the document

Example: The reaction produced a high yield under optimal conditions.¹

Reference List

The reference list should:

  • Be numbered according to order of appearance in the text
  • Include all sources cited in the text
  • Follow specific formatting for different types of sources

Citing Different Source Types

Journal Articles

Format:

Author 1; Author 2; Author 3; etc. Title of Article. Journal Abbreviation Year, Volume, Pages.

Example:

1. Doe, J.; Smith, A.; Johnson, B. New Developments in Organic Chemistry. J. Am. Chem. Soc. 2023, 145, 1234-1245.

Books

Format:

Author(s). Book Title, Edition Number; Publisher: Place of Publication, Year; Pages.

Example:
