Color Reproduction. Color illustrations will be considered for publication; however, the author will be required to bear the full cost involved in color art reproduction. Color art can be purchased for online only reproduction or for print + online reproduction. Color reprints can only be ordered if print þ online reproduction costs are paid. Rates for color art reproduction are: Online Only Reproduction: $225 for the first page of color; $100 per page for the next three pages of color. A custom quote will be provided for articles with more than four pages of color. A maximum charge of $525 applies. Print+Online Reproduction: $900 for the first page of color; $450 per page for the next three pages of color. Art not supplied at a minimum of 300 dpi resolution will not be considered for print.

Tables and Figures. Tables and figures should not be embedded in the text, but should be submitted as separate files or on extra sheets in the text. Again, authors are encouraged to use Microsoft Word. Number tables consecutively with roman numerals; a short descriptive title should appear above each table with a clear legend and any footnotes suitably identified below. Line art and photographs should be completely labeled and numbered consecutively with arabic numbers. The preferred width of submitted line art is 20 to 23 cm with capital lettering 4mm high, to accommodate reduction to single-column width. Captions should be typed on a separate sheet included in the files that contain the tables and/or figures.

Equations and Formulae. Mathematical: Mathematical equations should preferably be typewritten, with subscripts and superscripts clearly shown. It is helpful to identify unusual or ambiguous symbols in the margin when they first occur. To simplify typesetting, please use: (1) the ‘‘exp'' form of complex exponential functions; (2) fractional exponents instead of root signs; and (3) the solidus (=) to simplify fractions, e.g., 3=4, exp x 1=2. Please underline all mathematical symbols to be set italic and put a wavy line juder bold symbols. Other letters not marked will be set in roman type. Chemical: Ring formulae and other complex chemical matter are extremely difficult to typeset. Therefore, supply reproducible artwork for equations containing such chemistry. Long reaction sequences should be designated as ‘‘Schemes'' and treated like figures, i.e., keep artwork in a file separate from the text, indicate in the margin an appropriate position, and supply a separate list of scheme captions. Where necessary, individual chemical formulae can be identified with bold arabic numbers. Chemical equations referred to in the text should be indicated with arabic numbers set over to the right in parentheses. Marking: Where chemistry is straightforward and can be set (e.g., single line formulae), please help the typesetter by distinguishing between e.g., double bonds and equal signs, and single bonds and hyphens, where there is ambiguity. The typesetter finds it extremely difficult to identify which symbols should be set in roman (upright) or italic or bold type, especially where the paper contains both mathematics and chemistry. Therefore, please underline all mathematical symbols to be set italic and put a wavy line under bold symbols. Other letters not marked will be set in roman type.
