N. Legaysommaire et F. Legay, ISOTOPE EFFECTS IN THE PHOTOCHEMICAL FORMATION OF HHGCH3 AND DHGCD3 IN NITROGEN AND METHANE MATRICES, Chemical physics, 211(1-3), 1996, pp. 367-375
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.
