Comparisons are made between different methods of introducing the principle of detailed balance in far-wing line shape theories. In particular, it is shown that by symmetrizing the operators in the quasistatic formulation of Ma and Tipping [J. Chem. Phys. [bold 95], 6290 (1991)], one can obtain the same results for the symmetrized matrix elements of the relaxation operator and their frequency detuning that were introduced in an [ital ad] [ital hoc] way in the resonant quasistatic formulations of Boulet and co-workers [J. Chem. Phys. [bold 91], 2163 (1989); [bold 94], 6406 (1991)].
