I've sent a zipped copy to the original author so it will be available as part of the distribution.This dictionary is obviously designed for use by chemists, in particular organic chemists and it would be really useful to extend this to other scientific or technical dictionaries. I'm not sure but you may need to log out and log back in again to get it to be used by all applications.

The dictionary used by iWork is "username/Library/Spelling/en", if you have already created a custom dictionary for iWork, you will need to append this dictionary file to the end of your current custom dictionary. I thought it would be useful to convert the dictionary to a format that would be compatible with iWork, (actually I think it is used by all Mac OS X applications).
