Citing Physical Property Data Using ACS Style

ACS Style Guidelines for Citing Physical Property Data

The purpose of the citation is to provide sufficient detail so that someone else can locate the data.  Page numbers may not exist when citing online sources of data and therefore it may be necessary to indicate information like the CAS Registry Number or the entry name so that someone else can locate the exact information that was cited.

The ACS Style Guide provides a few examples for citing data but does not include examples of the wide variety of online sources that are available. Access the Citing Data using ACS Style ( University of Manitoba) guide to find more examples of how to cite physical property data like melting points and spectra or click on the links below to see examples of citations.

Introduction to ACS Style

ACS style is the standard style used in chemistry.  The ACS Style Guide is available in print and online format.  Chapter 14 of the guide includes examples of different types of references. References are arranged either by number or alphabetically by author, depending upon which type of in-text citations are used. 

In–Text Option

Organization of Reference List

 

Superscript1

(most common style)

Arranged numerically - numbers are listed in the text starting with 

Example:

Italic numbers (1)

Arranged numerically - numbers are listed in the text starting with (1)

Example: 

  • Oscillation in the reaction of benzaldehyde with oxygen was reported previously (6).
  • Jensen (6) reported oscillation in the reaction of benzaldehyde with oxygen.

Author/year  (Smith, 2012)

(not very common - used primarily in books)

 

Alphabetically by author

Example:

  • Oscillation in the reaction of benzaldehyde with oxygen was reported previously (Finnegan et al., 2004)
  • The primary structure of this enzyme has also been determined (O'Brien and Alenno, 2005; Axelrod, 2003).

 

Journal Abbreviations

Can I use a Citation Generator?

Some Citation Generators can create some citations in  ACS style for books or journal articles.  You should always check to make sure that the generated citation matches the requirements of the style used. Citation Generators DO NOT abbreviate the name of the journal which is required in ACS style.  To find the correct abbreviation consult the CASSI Source Index.

Caution sign  USE THE INFORMATION GENERATED AS A STARTING POINT FOR YOUR CITATION ONLY.  YOU NEED TO CHECK ALL PARTS OF THE CITATION INCLUDING AUTHOR NAMES, CAPITALIZATION, JOURNAL NAMES (AND JOURNAL ABBREVIATIONS IF NECESSARY) AND PUNCTUATION.

 

Online Citation Generators

These generators include many different citation styles and can help you cite journals, books or websites. ZoteroBib, BibMe and Cite This for Me are just a few examples.  There are many other citation generators. Some features available for free; advanced features may require a subscription.

 

Managing Your References

Citation Management Software can help you organize and cite your references.  See the Citation Management Software guide for more information on EndNote, Zotero and Mendeley.
