The effects of quadrupole relaxation on the relative linewidths of the double resonance spectrum of a molecule in the liquid state are described. Only the special case is considered for which the broadening of individual components by quadrupole relaxation is not great enough to lead to complete collapse of a spinmultiplet. It is assumed that line separation is large compared to linewidth. The calculations are illustrated for the ammonia molecule.
