Resumo
The relaxation parameters of lines of the P, Q, and R branches of the ammonia ν2 band are calculated in the case of self-broadening with the effects of collisional interference of doublet components taken into account. It is shown that the cross-relaxation parameters do not exceed, as a rule, several percent of the values of the self-broadening coefficients and, consequently, the isolated line approximation is applicable in a wide pressure range. The calculated results are compared with experimental data.
