Photochemical Preparation and Spectroscopic Characterization of H4 and Its Decay Products
Abstract
Three areas of investigation on H4 and its decay products are described: (a) Studies of the effects of rotational and vibrational excitation on the rate of electronic quenching via the maximum ionicity excited state (MIES) for the system H2 (B) + He, and on the rates for angular momentum reorientation for H2(B) in collision with HE, Ne, Ar and molecular hydrogen are reported; (b) A highly sensitive scheme for state-to-state detection of H2 and an intense pulsed hydrogen cluster source were developed in an extensive but unsuccessful search for high-lying Rydberg states of the H4 moiety; (c) Results of a systematic investigation made to resolve rotational structures in the vibrational spectra of H5+ (H2 molecules solvated in a H3(+)= core) show that additional work is required in order to obtain definitive identification of the rotational structures.
