Phase Space theory of Chemical Reactions :
A quantum or classical statistical limit of chemical reactions based on asymptotic densities of states with conservation of energy and angular momentum. A limiting case, perhaps valid for complex reactions.

Theoretical methods of quantum dynamics :
Exponential (Magnus) expansion of the time evolution operator;
Unitary time evolution via Iterative Lanczos propagators;
R-matrix propagation for solution of close coupled quantum scattering equations,
Direct methods for resonances and Siegert parameters;
Basis Representations for nuclear dynamics;
     Discrete variable representations
     Distributed Gaussian basis representations
     Sequential diagonalization/truncation (adiabatic/sudden bases)
Applications to photodissociation, chemical reactions, vibration/rotation spectroscopy of polyatomic molecules, surface scattering.
