Research will be carried out in four areas:                                     1)   Proton tunneling in nearly symmetric wells:  based on our                       previous characterization of the indigo/benzoic acid                            crystals the system will be used to investigate tunneling                       dynamics in molecular crystals by means of narrow-band laser                    methods and picosecond pump-probe techniques.                              2)   Proton dynamics in asymmetric wells:  femtosecond laser                         methods will be used to study the nature of the dynamics of                     proton motions in molecular crystalline materials containing                    intramolecular hydrogen bonds; the nature of the exciton                        bands in such systems which undergo rapid proton motion will                    be explored.                                                               3)   Dynamics of excitations in polymers of silicon:  the                            optically generated excitations on the long silicon chains                      of the polysilanes will be studied by picosecond and                            subpicosecond methods.                                                     4)   Energy disposal mechanisms in organic solids:  optical and                      infrared pump-probe experiments will be carried out to study                    the mechanisms of cooling vibrationally hot molecules in                        molecular solids.
