In addition, articles made publicly available through our ACS AuthorChoice/ACS AuthorChoice+12 Creative Commons CC-BY option can also be text and data mined for commercial purposes.
Articles not published under an ACS AuthorChoice license can only be text and data-mined through a separate license with ACS.
