    Abstract

    The photodissociation of dimethylmercury, Hg(CH3)2, in dilute argon matrixes is induced efficiently by ArF (193 nm) and inefficiently by KrF (248 nm) laser irradiation. The reaction products are identified by their IR absorption and UV absorption and luminescence spectra. Upon ArF photolysis, ethane remaining in close proximity of a Hg atom (Hg‚C2H6) is the main reaction product. The Hg‚C2H6 complex is destroyed by KrF radiation with formation of HHgC2H5, which is photolyzed, giving HgH2 and ethylene. Unidentified near UV emission bands recorded during irradiation are tentatively assigned to an unstable Hg‚CH3 complex.
