Today i was studying writing on my pc some schemes taken in lessons in order to create order in my annotations of human pathology.
I needed a font for write chemical formulas and reactions and so i've decided to try to search in internet if it exists.
I've found it in this site: http://www.scs-intl.com/frameload.htm?/chemfont.htm
There are two fonts that are free and perfect. You have only to download them and put the .ttf files on the "fonts" directory of Windows.
This is written on the site:

ChemFont97 is a Windows font package that simplifies the entry of chemical equations and notation. The font includes all upper and lower case Greek characters, superscripts, subscripts, many chemistry-specific symbols like reaction arrows; and of course, the Roman typeface for normal typing. ChemFont97 comes in two styles: serif, which is like Times New Roman, and sans-serif, which is like Arial.

Another one interesting, useful and free (for PCs and Macs)is here: http://www.rsc.org/education/teachers/learnnet/RSCfont.htm

The Royal Society of Chemistry font is a specialist chemistry font that may be downloaded free and used on PCs and Macs. This font allows chemical symbols to be introduced easily into Word documents.
