Dr. Hai-Lung Dai is supported by a grant from The Experimental                  Physical Chemistry Program to study intermolecular potential                    functions for van der Waals complexes using molecular beam and                  laser spectroscopic methodology.                                                                                                                                Dr. Dai is using stimulated emission pumping (SEP) on van der                   Waals complexes to study the interaction potential between                      molecules and the dynamics of reaction and energy transfer of                   vibrationally excited molecules.  Model intermolecular                          potentials are being developed and tested with the van der                      Waals mode frequencies and the complex structures which are                     experimentally observed.  Vibrational predissociation of the                    complexes is being examined as a function of both the                           vibrational energy and the vibrational mode.                                                                                                                    Stimulated emission pumping will also be used to prepare a                      large quantity of complexes in a selectively excited                            vibrational level.  The product vibrational state distribution                  after predissociation will be probed.  Correlation between the                  excited level and the product states may reveal the effect of                   attractive forces in vibrational energy transfer and the                        propensities of low energy collision-induced V-V transfer.
