“…Benzyl has also been introduced into jets by the reaction of Ba atoms, produced by laser vaporization, with benzyl chloride seeded in He expansions. 177 The trimer SiC2 has been observed in conjunction with laser ablation studies in nozzles. 156 It may be expected that the ablation work on metals and metal compounds (described below) can be extended to produce oxides, nitrides, silicides, etc.…”

“…For example, by reacting metal atoms with organic halides, cold metal halides and organic radicals can be produced and experimentaly studied. This we have recently exemplified by the reaction of Ba with benzyl chloride to produce adiabatically cooled benzyl radicals (Cai et al 1989b). Similarly, by entraining in the carrier gas N 2 O, oxygen or other reactive gases, metal oxides, hydrides, carbides or nitrides can easily be studied.…”

Vaporizing solid samples of metals and semiconductors with a YAG Laser is a method well suited for producing molecules and clusters of those materials. The clusters are examined by either laser-induced fluorescence (LIF) or mass spectroscopic methods. The technique is valuable for both gas phase and matrix studies. The method is described and some applications, studying either the structure of small metal molecules or their reactions, are reviewed, with emphasis on our recent results from the LIF studies of LiBe, AI 2 and the reaction of AI with oxygen, yielding A120. For larger clusters, Ion Cyclotron Resonance is an extremely valuable method, as we demonstrate by its application to the reactions of small charged silicon clusters with strong oxidising agents.

The collisional deactivation of vibrationally highly excited benzyl radicals in the ground electronic state has been investigated. Vibrationally excited benzyl radicals have been generated using the fast dissociation of vibrationally excited ethylbenzene prepared from UV absorption followed by fast internal conversion. Subsequent to complete collisional deactivation the benzyl radicals have been reexcited by the absorption of a further UV‐photon also followed by fast internal conversion. Once again the collisional deactivation of the benzyl radicals has been monitored by time‐resolved UV absorption spectroscopy. Average energies transferred per collision have been determined by comparison of absorption‐time profiles with different initial vibrational energies. It was found that the rate of collisional deactivation of the open shell benzyl radical is almost identical to the rate of collisional deactivation of the closed shell hydrocarbons of similar size.
