Zeeman rotational tunneling level-crossing spectra have been interpreted on the assumption that only single noninteracting groups contribute to the spectrum. In this note, we report the results of an analysis which takes into account two noninteracting groups, in which case the inter -group interactions become important. This analysis agrees with the accepted interpretation of the ground state manifold wherein the F level is triply degenerate.

The gaseous species Zn, ZnCl, and were generated in an effusion cell by reaction of with ZnO(s) near 1400 K, and were identified and monitored by mass spectrometry.Equilibrium constants were evaluated for the gaseous reaction from ion intensities measured over the range 1336–1436 K and used to derive the third law enthalpy change and the dissociation energy This result is in good agreement with an earlier value derived from equilibrium measurements made by monitoring the electronic spectrum of ZnCl(g) in equilibrium with gaseous Zn and The results are useful in estimating the thermochemicalproperties of gaseous ZnOH and for chemical modeling applications.
