Jet-Cooled Fluorescence Excitation Spectra and Carbonyl Wagging Potential Energy Functions of Cyclichin the ring. The C=O and C=C stretching frequencies occur at 1418 and 1357 cm. for the d. molecule. The ring-twisting frequency for the .. state occurs at 274 cm.. Previous electronic absorption measurements had resulted in a misassignment for this motion..The jet-cooled fluorescence excitation spe

Dynamics of Non-Rigid Molecules: The Exploration of Phase Space Via Resonant and Sub-Resonant Coupliveraging neglects the effect of the sub-resonances which, for physically realistic couplings can have amplitudes as large or larger than the resonance. We discuss an alternative approach for the perturba-tive analysis of coupled non-linear oscillators designed to incorporate the effect of sub-resona

The Structure, Symmetry, and Properties of Non-Rigid Moleculesthe basis of the results of high quality . calculations, the dynamic calculations of the ro-vibrational spectra, and experimental spectroscopic measurements at high resolution. Molecular species with large amplitude motions between formally chemically bonded atoms (e.g. LiCN, LiBH., C.H.., ArH.. and others) have been considered as examples.
