Marcel Nooijen carries out research in theoretical chemistry. His 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.
