SENIOR PRODUCTION EDITOR Charles R. Bertsch © Copyright, 1968, by the American Chemical Society. Published monthly by the American Chemical Society at 20th and Northampton Sts., Easton, Pa. 18042. Accounts of Chemical Research publishes concise, critical re views of research areas currently under active investigation. Most articles are written by scientists personally contributing to the area reviewed. Reviews need not be comprehensive. In deed, they may be concerned in large part with work in the author's own laboratory, providing that relevant contributions by other investigators are mentioned sufficiently to place the author's research in perspective. Articles should be directed concurrently to a general audience of research-minded chemists and to scientists directly concerned with the subject of the article. In general, the first four or five pages of the manuscript should be directed mainly to the general audience, providing background and orientation as well as dis cussion of terms or concepts of special value in the field of the article. Because of the limited amount of journal space available, the usual allotment per article is five or six journal pages. This corresponds roughly to a total of 20-25 pages of manuscript, bibliography, and drawings. Most reviews are written in response to invitations issued by the Editor. Unsolicited manuscripts are also considered for publi cation. Manuscripts for publication and editorial correspondence prior to acceptance of manuscripts for publication should be sent to JOSEPH F. BUNNETT, Editor, Accounts of Chemical Research,
University of California, Santa Cruz, Calif. 95060. Manuscripts should be prepared in accordance with the general instructions given in the American Chemical Society "Hand book for Authors. ' ' Manuscripts should be typed, double-spaced, and they should be submitted in triplicate. Additions and Corrections will be published once yearly, in the December issue.
Extensive or unusual alterations in an article after it has been set in type are made at the author's expense, and it is understood t h a t b y requesting such alterations the author agrees to defray the cost thereof. The American Chemical Society and the Editors of Accounts of Chemical Research assume no responsibility for the statements and opinions advanced by authors of articles. Correspondence regarding accepted papers, proofs, and re prints should be directed to Research Journals Production Office, American Chemical Society, 20th and Northampton Sts., Easton, Pa. 18042.
