Abstract
By 249 nm irradiation of CH4/N-2 or CH4 matrices doped with mercury, H HgCH3 is formed and studied through FTIR spectra. DHgCD3 has been also produced in Hg/CD4/N-2 and Hg/CD4. The annealing and temperature effe cts have been discussed for comparison with previous experiments with molecular Hz instead of CH4. The study of mixed matrices Hg/CH4/CD4/Ar , Hg/CH4/CD4/N-2 and Hg/CH4/CD4 has shown a strong isotopic effect, th e insertion reaction of Hg(P-3(1)) is much easier in the CH than in th e CD bond.
