Cite ACS Style

Select one of the three methods below to cite in-text references:

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.
