Introduction
The following are handouts from Professor Ronald Lovett's Chem 521 Introduction to Quantum Mechanics Department of Chemistry at Washington University in St. Louis, MO. A first-year graduate level course in quantum mechanics.

Regarding these handouts, readers should note the following:

• Topics are arranged alphabetically.  They are not arranged in any systematic order by topic.
• Handouts were used to augment and clarify class discussions addressing a specific topic relative to quantum mechanics. The intent was for students to read the handouts not as a continuous whole but rather as the enlightenment of a specific topic relative to QM.
• Professor Lovett often tailored handouts to specific QM classes depending upon overall class strengths and/or weaknesses.  Hence, some handouts with the same title are significantly different.  In some cases, the reader will see multiple versions of the same handout designated by a different creation date. This means there were significant changes from previously dated handouts on the same topic
• A few of the handouts veer away from quantum mechanics. These were often written for faculty colleagues who came to Professor Lovett with a specific question related to Statistical Mechanics or Quantum Mechanics
