Bio: Dr. Kirtman received his Ph.D. from Harvard University in 1960. He was a postdoctoral at
the University of Washington (Seattle) and a member of the UC Berkeley faculty before
coming to UC Santa Barbara in 1965. He has received the Distinguished Teaching Award
of the UCSB Academic Senate (1983) and the ICCMSE 2005 Prize for Theoretical and
Computational Chemistry.


Current Research

My research deals with the theory, as well as computation, of electronic structure and properties. Two general topics are of primary current interest, namely vibronic (vibrational/electronic) effects in structure and spectroscopy and the interaction of molecules or materials with electric and magnetic fields. Some specific areas under investigation include: (i) quasilinear polymers in electric and magnetic fields; (ii) giant vibrational contributions to linear and nonlinear optical properties of conjugated organic systems; (iii) construction of reduced dimensionality potential energy surfaces for chemical reactions; (iv) calculation of molecular Franck-Condon factors; (v) treatment of impurities, defects, and localized states in 1-, 2- and 3-D systems; (vi) electric field polarization of ionic solids, carbon nanotubes, fullerenes, and hydrogen-bonded systems; (vii) optimized effective potentials in Density Functional Theory; (viii) advanced methods for treating vibrational anharmonicity; (ix) properties of electrides; (x) design of nonlinear optical materials; and (xi) computation of electronic structure by combining at the same or different levels of approximation.
