The heat of formation of a compound is among the most important quantities in
the chemical understanding of that species. Nonetheless, of the 80 million or so
known species containing carbon (organic compounds), this quantity is known from
experiment for about only 10 thousand. On many occasions I have needed
information about a specific compound for my chemical research and many times
the data have never been determined. This is even more the case when the
compound itself is unknown. Calculational quantum chemistry provides both the
mathematical and the computational framework to obtain the necessary numerical
data so that I and others in chemistry and other related sciences can achieve
the more qualitative understanding that is the characterizing strength of my
interdisciplinary, international research.
