Laser Fluorescence Excitation Spectrum of Jet-Cooled Tropolone: The A(1) B sub 2 - X(1) A sub 1 System

摘要

Proton and electron tunneling processes are well known to be of fundamental importance to physics, chemistry, and biology 1 but the extent to which massive skeletal atoms can participate in such tunneling processes in polyatomic molecules is an important and poorly understood facet of the topic. Some intramolecular tunneling processes, e.g., internal rotation by a symmetric top moiety, are not strongly coupled to other intramolecular motions of the molecule and reduce to one-dimensional problems. 2 Tautomerization tunneling reactions with large amplitude motion by an H atom and shifting of the equilibrium positions of the heavy atoms are of greater chemical interest. In the present article highly mode-specific tunneling doublet separations are reported for normal tropolone, C 7H 5O(OH), a molecule which appears to be particularly well qualified for studies of the type under discussion. reprints, hydrocarbons.
