This research, part of the Experimental Physical Chemistry                      Program, uses laser techniques to explore the electronic                        structure and intermolecular interactions that determine                        chemical properties in prototypical organic molecules in the                    solid state.  The data obtained, together with their                            interpretation using available and developing models, are                       utilized to understand the chemical properties, dynamics and                    electronic structures of polyene systems.  The results of this                  research are useful in understanding many technologies varying                  from optical memories to the molecular basis for vision.                                                                                                        Laser-based photochemical hole burning techniques will be                       utilized to measure 1- and 2-photon spectra and excited state                   dynamics for well defined polyenes substituted into mixed                       crystals at liquid helium temperatures.  The data obtained will                 elucidate the fundamental mechanism by which a linear polyene                   isomerizes in a molecular cavity.  In addition to providing new                 information on cis to trans isomerization, these studies will                   explain the connection between isomerization and nonbonded                      interactions between guest and host molecules.
