 Title: VIBRATIONAL DEPENDENCE OF THE ROTATIONAL STRUCTURE AND DISSOCIATION RATES OF THE A STATE OF $NH_{3}, NH_{2}D, NHD_{2}$ AND $ND_{3}$, Creators: Henck, Steven A.; Yan, W.- B.; Lehmann, K. K. Issue Date: 1989 Publisher: Ohio State University Abstract: Microwave-ultraviolet double resonance experiments on the pre-dissociative first excited electronic state of ammonia are presented. Using microwave-ultraviolet double resonance, we are sensitive to only a few rotational transitions at a time. Thus, we have been able to determine the rotational constants and the rotational dependence of the dissociation rate for $\nu_{2}-0-4$. We have found that Fermi resonance is needed to explain the vibrational state dependence of the dissociation rate.
