MASS-SELECTIVE LASER PHOTOIONIZATION. R. E. Smalley, Department of Chemistry, Rice University, Houston, Texas 77001 Within the past several years, new developments in laser technology have enabled a fantasitc advance in the spectroscipic investigation and analytic detection of polyatomic molecules. In many cases we can now reach single molecule counting sensitivity with selectivity not only to a particular type of molecule, but even to a particular state of that molecule-all within a time frame of less than ten billionths of a second! This talk will discuss recent developments and applications of this multicolor, mass-selective laser techniquye in the rather exotic environment of a hypersonic molecular beam. Included in the set of examples will be probes of (1) triplet formation and decay in aromatic molecules, (2) molecular excimers and exciplexes, and (3) metal cluster and dynamics in an ultracold pulsed hypersonic beam.
