Citation Guide: ACS (American Chemical Society)

Guide to various citation styles, including tips for citation analysis and writing.

In text citation

  • By number (italics)
    The synthesis of the compound has been described previously (1).
  • By superscript
    The synthesis of the compound has been described previously.1
  • By author name and date
    The synthesis of the compound has been described previously (Johnson, 1902).

With numerical citations, references should be numbered sequentially. If a reference is repeated, do not give it another number; rather, use the original reference number.

With author name citations, use both names if a reference has two authors (Jones and Smith, 2002). If there are more than two authors, use the first name followed by et al. (Harris et al., 2001).

References list

Creating a Bibliography

  • Arrange the references in your bibliography based on the method used for in-text citations. If numerical citations were used, then arrange references at the end of the paper numerically. If author names were used, arrange alphabetically.
  • All references end with a period.
  • Do not leave blank lines between references.
  • Journal article titles and book chapter titles are not essential, but they are considered desirable.
  • If a book as a whole is used, pagination is not necessary.
