Research

Marcel Nooijen's long term goal is to develop accurate wave function based electronic structure methods that are applicable to general open-shell systems, in particular transition metal compounds. The electronic structure technique should be coupled to an efficient scheme to describe non-adiabatic nuclear dynamics such that one can make direct comparisons with experimental results. The ideal electronic structure methodology would be a local, multireference coupled cluster method, combined with an efficient explicit correlation (r12) technique, and including important relativistic effects. Nuclear dynamics would be based on vibronic model Hamiltonians obtained from a suitable diabatization of the electronic states.

Teaching

Marcel Nooijen teaches both undergraduate and graduate courses. Course offerings have included topics in quantum mechanics, computational chemistry, thermodynamics, statistical mechanics and chemical kinetics.
