Spectroscopic and Dynamical Studies of Acetylene and Hydrogen Cyanide: S/Sub 0/ Surfaces, Unstable Isomers, and Triplet States: Final Technical Report

摘要

Progress is reported in the following areas of research: statistical properties of C sub 2 H sub 2 spectra in the 28,000 cm sup -1 region; properties of C sub 2 H sub 2 X-bar sigma /sub g/ sup + levels in the 11,400-15,600 cm sup -1 region; a spectroscopic study of the acetylene-vinylidene isomerization; an unsuspected Fermi perturbation in the acetylene A-bar 'Au 3 nu sub 3 level; acetylene quantum beats and anticrossing spectroscopy; and unimolecular decomposition of acetylene; determination of the heat of formation of the CCH radical.
