This new volume presents a selection of articles on topics in the field of physical chemistry. Physical chemistry is the study of how molecular and atomic levels of materials behave and how chemical reactions occur, knowledge which is relevant in nearly every area of chemistry. It covers diverse topics, from biochemistry to materials properties to the development of quantum computers. Dr. Harold H. Trimm was born in 1955 in Brooklyn, New York. Dr. Trimm is the chairman of the Chemistry Department at Broome Community College in Binghamton, New York. In addition, he is an Adjunct Analytical Professor, Binghamton University, State University of New York, Binghamton, New York. He received his PhD in chemistry, with a minor in biology, from Clarkson University in 1981 for his work on fast reaction kinetics of biologically important molecules. He then went on to Brunel University in England for a postdoctoral research fellowship in biophysics, where he studied the molecules involved with arthritis by electroptics. He recently authored a textbook on forensic science titled Forensics the Easy Way (2005).
