ACS Citation Style

The American Chemical Society (ACS) citation style is used for academic papers written in the field of chemistry.

In-text citations

When writing in-text citations in ACS Format, please consider the following example as a guide:

References in the text should be cited in one of three ways:

  • by an italic number
  • or by superscript number
  • or by author name and date

References should be numbered sequentially.  If a reference is cited more than once, it does not receive a new number.  If citing more than one reference at a time, include reference numbers in increasing order separated by commas.

Italic Number Example:    …preparing N-(p-nitroaryl)amides (2).
Author Name and Date Example:    …preparing N-(p-nitroaryl)amides (Stern and Cheng, 1995).
