Infrared Photon Initiated Conformer Interconversion, Fourier Transform Microwave Spectroscopy of Hydrogen Bonded Trimers, and Study of Conformer Cooling in Supersonic Expansions

C-H stretch fundamentals were excited by an IR OPO laser in 2 molecules having conformers. Because the barrier for interconversion is lower (higher) in methyl vinyl ether (methyl nitrite) than IR photon energies, IR fluorescence spectra showed conformational interconversion occurred (did not occur). For the first time, well defined energy in collisionless conditions was deposited in a ground electronic state molecule with subsequent intramolecular energy flow perturbing the equilibria between conformers (methyl vinyl ether).
