Marcel Nooijen

• Electronic Structure Theory
• Vibronic coupling and non-adiabatic nuclear dynamics
• Simulation of vibronic spectroscopy
• Coupled Cluster Theory for excited states
• Multireference methods in transition metal chemistry

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.

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