Observation of several new electronic transitions of the SrOH free radical

We report four new electronic transitions of the SrOH free radical, the C 2Π-X 2Σ+, D 2Σ+-X 2Σ+, E 2Σ+-X 2Σ+, and F 2Π-X 2Σ+ transitions. SrOH was prepared in a supersonic jet by laser ablation and spectra were recorded using laser-induced fluorescence. The C 2Π-X 2Σ+ excitation spectrum shows complex vibronic structure which is attributed, at least in part, to Renner-Teller activity in the excited electronic state. This is supported by dispersed fluorescence spectra which show substantial bending mode activity in the emission from several different excited vibronic levels. It is suggested that the prominence of nominally forbidden vibrational features arises from a large change in permanent electric dipole moment between the X and C states. In turn, this suggests that the C 2Π state of SrOH is the analogue of the reverse-polarized 2 Π states known for the alkaline-earth monohalides, i.e., the highest occupied π orbital points towards the O atom. The D 2Σ+-X 2Σ+, E 2Σ+-X 2Σ+, and F 2Π-X 2Σ+ spectra are much simpler than the C-X system, being dominated by regular structure in the Sr-O stretching vibration.

ELECTRONIC MATRIX ISOLATION SPECTROSCOPIC STUDIES OF THE GROUP IIA METAL-WATER PHOTOCHEMISTRY.

Results are reported of an investigation of the electronic structures of the Group IIA metal atom hydration reaction intermediates (M. . . OH//2 adducts) and their subsequent photolysis products (HMOH and MOH). For the adduct, the metal-water interaction is sufficiently strong so as to perturb significantly the electronic structure of the metal atom, which results in a unique band structure for the adduct that is red-shifted from the metal atomic resonance transition. Selective photolysis studies are conducted to assist in deconvoluting the complex band structure of the adduct. Molecular orbital theory is invoked to interpret the nature of the ground and excited states of the adduct.
