ACS (American Chemical Society) Style Guide
Developed by the American Chemical Society, the ACS Stye is generally used for research papers and journal articles in the field of chemistry.
Each citation consists of two parts: the in-text citation and the reference list. The in-text citation provides brief identifying information on the cited work. The reference list is a list of sources that provides full bibliographic information at the end of the paper or article.
In the ACS Style, references can be cited in one of three ways: by italic number, by superscript number or by author name and date. For this class the superscript number style is recommended.
The ACS Superscript Number Style
In the ACS superscript number style, citations are numbered in the list of references and cited in the text by the superscript number of the citation.
Citations within the text:
For in-text citation, the superscript number can be at the end of the cited information or within the cited information:
Examples of in-text citation
At end of cited information:
Oscillation in the reaction of benzaldehyde with oxygen was reported previously.³
Within the cited information:
Smith³ states that oscillation in the reaction of benzaldehyde with oxygen was reported previously.
If a reference is cited more than once, it does not receive a new number. If citing more than one reference at a time in the text, include reference numbers in increasing order separated by commas.
Citations in the list of references:
The reference list provides the full details on the sources you used in the research for your paper.
Each entry will include the following reference components:
Citations in the list of references should be ordered by their superscripted numbers in the text (not alphabetically).
Use a hanging indent to format your references list indent (that is, all lines in a reference entry are indented except for the first line). Journal names and book titles are italicized.
To correctly abbreviate scientific journal titles (necessary for citing journal articles) use the Chemical Abstracts Service Source Index.
