Changes to Published Documents for World Wide Web Presentation

If you have problems reading documents let me know (g.p.moss@qmul.ac.uk).

In order to make material readable on World Wide Web a number of modifications have been made. Greek and other symbols which are not available as a basic ASCII symbol are mainly provided as a graphic representation. Increasingly the font symbol is being used, but an alternative graphic representation may also be provided. The size and position of a graphic representation may not match the font size of the browser and allowance should be made for this. Please consult the printed version if in doubt.

Subscripts e.g. ethanol C₂H₅OH
Superscripts e.g. sodium chloride Na⁺Cl^-
Greek, etc e.g. -amino acid (graphic Greek) or a-amino acid (using symbol) or α

Some accents are not available and may be ignored.

Due to the lack of control over the format beware of molecular formulae which may be spread over two lines with the split before or after a subscript number.

Last update 18 January 2010.
