- Guidelines for illustrations -
l Line illustrations (graphs and spectra)
These
guidelines are designed to assist authors with the production of high quality illustrations.
All illustrations must bear on the back the names of the authors, the
title of the paper and the number of the figure or the scheme. They must be
black on white paper.
Illustrations should be prepared for a single (81mm) or a double column
(172 mm) width. Single column is preferred. The maximum page depth is 166 mm.
For best results, artwork should be submitted at its full size so that
reduction is not required.
If oversized figures cannot be avoided (e.g. hand drawn) these
should be appropriate for reduction. Reduced copies of these figures, in the
size they are due to appear, should also be submitted.
Line illustrations
(graphs and spectra)
The lines should be black and of an adequate and even thickness
Broken, dotted and dot-dash lines can be used
Particular care should be taken to ensure that the lines in the spectra
are of adequate thickness
Lettering should be no smaller than 7 pt Times New Roman and lines no
thinner than 0.5 pt.
Lettering and lines should be of uniform density throughout the figures
Labelled atoms in ORTEP (or other) diagrams should have atom numbers in
parenthesis, e.g. Fe(1), C(44)
For graphs, axis labels should use SI units, separated from quantities
with ‘/’ not brackets, e.g. l/nm, concentration/mol L-1,
103 (T/K)-1 (see http://www.iupac.org/publications/books/author/mills.html)
Units should be expressed in the form, e.g., g cm-3
rather than g/cm3
Symbols representing physical quantities should be given in italics, e.g.
t/s, J/Hz
Curves should be labelled (a), (b), (c) etc., and further information
given in the figure legend
Graphs should have only the requisite minimum of scale divisions marked
by numerals
Data points must be shown sufficiently large to be distinguishable. Whenever
possible, they should be marked with one or more of the following symbols:
For computer generated artwork, tints or shadings should be avoided
Figures, schemes and structures should be drawn for single or double
column widths
Structures should be numbered with bold Arabic numerals, e.g. 1,
2
The following organic ligand abbreviations may be used: Me, Et, nPr,
iPr, nBu, sBu, tBu, Ph, CO2R,
CO2H
One variable univalent substituent is indicated by R; when more than one
independent variable general substituent is present, R1, R2,
R3, etc., should be used
A variable metal may be indicated by M, and variable ligands, by L1,
L2, L3, etc.
High quality original prints should be provided
Photographs should be unmounted, high contrast, positive, glossy prints,
unmarked and free of any oils
When necessary, the scale should be drawn on the photograph itself, and
not below
NB: Colour prints rarely reproduce satisfactorily in black and white
These will only be made available in the electronic supplementary
