The Mnemonics Page
by Dean Campbell, Bradley University Chemistry Department
My intention is to create an informal repository of useful mnemonics on a variety of topics, especially chemistry. Please contact me at firstname.lastname@example.org if you have suggestions for the page. The people mentioned are my sources for these mnemonics, not necessarily the originators for the mnemonic.
