An investigation of dynamics and intermolecular interactions in                 molecular solid state systems.  Picosecond and subpicosecond                    nonlinear experiments combined with ultrahigh resolution                        spectroscopy, conventional optical spectroscopy and theory are                  used to study isolated molecules in crystals and glasses, weakly                interacting molecules in impurity band systems, and strongly                    interacting molecules in pure crystal exciton systems.  In                      glasses by combining photon echo and other optical coherence                    experiments with optical holeburning experiments, acoustic                      measurements and heat capacities, a new and detailed picture of                 dynamics and intermolecular interactions in these nonequilibrium                systems is emerging.  In the impurity band problem, photon echo                 experiments are shown to be a direct observable for the                         concentration dependent delocalization of electronic excitations                in mixed crystal systems.  The application of phase related pulse               sequences, particularly the optical dipolar echo, to the impurity               band problem is described using a new approach for generating                   picosecond pulses with well defined phase relationships.  The                   applications of picosecond transient grating techniques to the                  investigation of exciton transport and polariton effects in pure                molecular crystals are discussed.  A combination of photon echo                 experiments and polarization grating techniques are used to                     examine the relationship between the mechanical motions of                      molecules and coupling to electronic states as observed by                      optical dephasing.
