C. Crepin et al., MECHANISMS OF THE ELECTRONIC RELAXATION OF THE HG(1P1) STATE IN LOW-TEMPERATURE MATRICES, Journal of physical chemistry, 98(13), 1994, pp. 3280-3284
The fluorescence-excitation and fluorescence spectra as well as the fl
uorescence decay times were recorded for Hg atoms excited to the 6P-1(
1) state by synchrotron radiation in Ar, Kr, Xe, N2, and CH4 matrices
and in Ar matrices with a low ammonia content. It was shown that seque
ntial decays from the 6P-1(1) to different 6(3)P(J) levels involve the
intersystem crossing and intramultiplet relaxation, the dependence of
the relaxation rate on the properties of the matrix being different f
or the two mechanisms.
