Current research author’s guide Manuscript requirements Five complete legible copies of the manuscript are required. They should be typed double or triple spaced on 22 x 28 cm paper, with text, tables, and illustrations of a size that can be mailed to reviewers under one cover. Duplicated copies will be accepted only if very clear. If pertinent references are unpublished, furnish copies of the work or sufficient information to enable reviewers to Title evaluate the manuscript. Use specific and informative titles. They should be as brief In general, graphs are preferable to tables if precise data as possible, consistent with the need for defining the subject are not required.

numbers of the article. Consult The ACS Style Guide for reference style.
Formulas and equations Chemical formulas should correspond to the style of ACS publications. Chemical equations should be balanced and numbered consecutively along with mathematical equations. The mathematical portions of the paper should be as brief as possible, particularly where standard derivations and techniques are commonly available in standard works.
Supplementary material Extensive tables, graphs, spectra, calculations, or other material auxiliary to the printed article will be included in the microfilm edition of the journal. Identify supplementary material as to content, manuscript title, and authors. Three copies of the supplementary material, one in a form suitable for photoreproduction, should accompany the manuscript for consideration by the editor and reviewers. The material should be typed on white paper with black typewriter ribbon or printed on high quality (300 dpi) laser printer. If individual characters for any of the material, computer or otherwise, are broken or disconnected, the material is definitely unacceptable. Figures and illustrative material should preferably be original high-contrast drawings or good prints of originals. Optimum size is 22 X 28 cm. Minimum acceptable character size is 1.5 mm. The caption for each figure should appear on the same piece of copy with the figure. Be sure to refer to supplementary material in text where appropriate. Supplementary material may be obtained in photocopy or microfiche form at nominal cost. Material of more than 20 pages is available in microfiche only. Photocopy or microfiche must be stated clearly in the order. Prepayment is required. See instructions at the end of individual papers. The supplementary material is abstracted and indexed by Chemical Abstracts Service. Subscribers to microfilm editions receive, free, the supplementary material in microfiche form from individual papers in any particular issue. For information, contact Microforms Program at the ACS in Washington, D.C., or call (202) 8724554. Research Communications. Please refer to Editorial Policy for guidelines on research communications.
Safety Authors are requested to call special attention-both in their manuscripts and in their correspondence with the editors-to safety considerations such as explosive tendencies, precautionary handling procedures, and toxicity.
Acknowledgment Include essential credits in an “Acknowledgment” section at the end of the text, but hold to an absolute minimum. Give meeting presentation data or other information regarding the work reported (for example, financial support) in a note following Literature Cited.
References Literature references should be numbered and listed in order of reference in text. They should be listed by author, patentee, or equivalent. In the text, just the number should be used, or the name should be followed by the number. “Anonymous” is not acceptable for authorship. If the author is unknown, list the reference by company, agency, or journal source. Do not list references as “in press” unless they have been formally accepted for publication. Give complete information, using abbreviations for titles of periodicals as in the Chemical Abstracts Service Source Index, 1907-1984. For periodical references to be considered complete, they must contain authors’ surnames with initials, journal source, year of issue, volume number, and the first and last page
