Author: Jean Demaison
Description: Molecular structure is the most basic information about a substance, determining most of its properties, determination of accurate structure is hampered in that every method applies its own definition of “structure” and thus result of different sources can yield significantly different results. Sophisticated protocols exist to account for these differences, nut until now, no textbook has been writteh to discuss such topics in a widely accessible manner. The textbook begins with a discussion of quantum chemistry and the concept of potential energy surfaces, quantum chemical computation and the structures and an-harmonic force fields. The reader is next introduced to the method of least squares and the problem of ill-conditioning, leverage points, perturbation theory, computational aspects of determining semi-experimental equiribrium structures, the determination of moments of inertia from spectra, and the treatment of resonances. The textbook also examines the determination of diatomic molecular potentials using semiclassical and quantum mechanical methods as well as position and distance averages.
