Chem 109 Lecture Notes, Spring 2011
These are the notes I am using to present my lectures.
They are here for the convenience of my students. Though I do my best to avoid and catch errors, they invariably creep in, so if you think there is a mistake, contact me via email and I will check it. The expansions and corrections I put
in during my lectures are not included. Use them at your own risk!
If you find errors in my notes, please inform me ASAP via e-mail:
