Abstract
INFRARED MULTIPHOTON EXCITATION (IRMPE) INDUCED PROCESSES INMEDIUM SIZED AD SMALLER POLYATOMICS EXHIBIT SELECTIVITY THATCAN BE CENTRAL IN APPLICATIONS. STATISTICAL THEORIES DO NOTAPPLY AND QUANTUM APPROACHES BECOME FORMIDABLE. A SEMICLASSICAL THEORY OF THESE PROCESSES IS TO BE DEVELOPED FOR POLLYATOMICS. THE FORMALISM WILL COMBINE THE SELF-CONSISTENT EIKONAL METHOD (SEM) AND TIME-CORRELATION FUNCTION (TCF) METHODS. TRAJECTORIES OF NUCLEAR COORDINATESAND MOMENTA SELF-CONSISTENTLY COUPLED BY AN EFFECTIVE POTENTIAL OF EHRENFEST TYPE TO ELECTRONIC AMPLITUDES PROVIDESCATTERING STATES FROM ASYMPTOTIC STATES. TCF EXPRESSIONS FOR CROSS-SECTIONS WILL BE ANALYZED FOR POSSIBLE DECOUPLING SCHEMES RELEVANT TO IRMPE INDUCED PROCESSES AND CORRESPONDING TO DIFFERENT TIMESCALES OF INTRAMOLECULAR DYNAMICS OF THE ENERGIZED POLYATOMIC. PRIMARY PROGRAM FUNCTION DEVELOPMENTS, TESTS, AND TRIAL RUNS ON MODELS INCLUDING ELECTRONIC EXCITATIOS WILL ESTABLISH FEASIBILITY. IN PHASE II, FOLLOW-ON IN DEPTH STUDY OF AN EXAMPLE IS PLANNED FOR COMPARISON TO EXPERIMENTS. THE THEORY IS EXPECTED TO DESCRIBE INTRAMOLECULAR VIBRATIONAL RELAXATION (IVR) INCLUDING THE VIBRATIONAL QUASICONTINUM AND YIELD NEW DYNAMICAL INSIGHTS INTO IRMPE INDUCED PROCESSES IN VIBRATING ROTATING ELECTRONICALLY INELASTIC POLYATOMIC SYSTEMS.
