Abstract
IN ORDER TO UNDERSTAND THE MECHANISM OF THE CHEMICAL OXYGEN-IODINE LASER (COIL) THE ROLE OF VIBRATIONALLY EXCITED 0 ( G) IN PROMOTING I DISSOCIATION MUST BE ASSESSED. THERE IS CURRENTLY NO LASERBASED TECHNIQUE CAPABLE OF MEASURING 0 ( G)(V) IN THE 10 MOLECULE CM CONCENTRATION RANGE EXPECTED IN A COIL CHEMICAL ENVIRONMENT. WE PROPOSED TO USE MULTIPHOTON IONIZATION SPECTROSCOPY (MPI) TO DETECT 0 ( G)(V) IN THIS SYSTEM. USING AN MPI TECHNIQUE PREVIOUSLY DEVELOPED BY THE PRINCIPAL INVESTIGATOR AND COWORKERS AT CORNELL UNIVERSITY TO OBSERVE VIBRATIONALLY RELAXED 0 ( G), WE WILL DEMONSTRATE THE ABILITY TO DETECT 02( G)(V) USING THE PULSED PHOTOLYSIS OF 0 AT 266 NM TO CREATE A DISTRIBUTION OF 0 ( G) VIBRATIONAL STATES. PHOTOLYSIS OF I( P / ) PRECURSORS IN EXCESS 0 WILL BE USED TO CREATE 0 ( G) VIA ENERGY TRANSFER IN ORDER TO ASSESS ANY INTERFERENCES FOR THE MPI DETECTION OF 0 ( G) WHICH MAY BE CHARACTERISTIC OF COIL SYSTEMS. DETECTION SENSITIVITIES OR LIMITS WILL BE REPORTED FOREACH VIBRATIONAL LEVEL AND SPECTRAL SIMULATION WILL BEDONE TO IDENTIFY THE 0 RYDBERG STATES THAT ARE INTERMEDIATES IN THE MPI PROCESS.
