Notes:
The absorption spectra in the 3P1←1S0 range and those of the prompt and long-lived emission components as well as their decay times are recorded for Hg atoms isolated in CH4, CD4, and mixed CH4/Ar matrices at T(approximately-equal-to)12 K using the dye-laser excitation. The results are compared to those obtained in the previous work for Ar, Kr, and Xe matrices. The rate of the 3P1(large-closed-square)3P0 intramultiplet relaxation is only slightly increased, while that of the 3P0→1S0 emission shows an important increase due to the coupling to internal modes of methane molecules. The evidence of this coupling is the vibrational structure of the emission spectrum involving nontotally symmetric ν2(E), ν3(F), and ν4(F) normal modes of CH4 or CD4 molecules.
