Abstract : Research Objectives: (1) Apply the Stimulated Emission Pumping (SEP) technique to highly excited vibrational levels of H2CO and D2CO. (2) Discover whether the rotation-vibration levels of H2CO/D2CO remain well organized at chemically significant levels of vibrational excitation. (3) Develop new multiple resonance spectroscopic techniques capable of measuring rotational energy transfer rates (RET) in highly excited vibrational levels of H2CO. (4) Develop statistical diagnostics for quantum ergodicity which are applicable to real SEP spectra of H2CO/D2CO. Keywords: Spectroscopy, Vibrational structure, Optical-optical double resonance, Molecular dynamics, Anharmonic vibrational constants, Electric dipole moment, Coriolis perturbations.
