Gruebele, Martin Sundaradevan, Praveen 2010-06-22T19:46:43Z 2010-06-22T19:46:43Z 2012-05-15T10:00:29Z 2010-05 2010-06-22T19:46:43Z 2010-05 Over 300 second excitated state to ground state vibrational transitions have been located, measured and assigned by dispersed fluorescence spectroscopy. The energies of these transitions were also fit with a spectroscopic effective Hamiltonian. These spectra show high activity in the v_1 and v_4 modes which is expected due to their known high Frank-Condon activity. However, predicted activity in other modes, particularly v_2 and v_6was not observed, quite likely due to the poor resolution of the higher energy spectrum. This made low-lying lines difficult to assign, thus hindering assignments of progressions in the higher region of this spectra. A higher resolution spectrum is required. A torsional potential energy surface was also constructed for the 2-fluoroethanol molecule, in an attempt to make theoretical predictions and corroborate known experimental work on the molecule. This surface includes zero-point energy (ZPE) corrections, to see if it would lower the torsional barrier significantly. It did not. A computer program used to predict potential couplings in a tier model of IVR is also presented.
