When you quote or paraphrase from a source (book, article, or webpage) in your paper, you need to insert an in-text citation.
In ACS papers, references can be cited in text in three different ways. Ask your instructors which method they prefer!
Italicized numbers in parentheses
Author name and year of publication in parentheses
Numerical Reference Methods (Superscript or Italicized)
Author Name and Year Parenthetical Reference Method
Citing More Than One Reference at a Time
If you are using a quotation with 50 words or more, indent on both sides to make a narrow column. Do not use quotation marks.
