Microwave resistivities of the singlet-ground-state systems TmX, PrX(X=N, P, As, Sb, and Bi) and Pr3Tl, have been measured. The crystal-field splittings of Tm3+ and Pr3+ in these systems have been obtained by comparing our resistivity data with Hirst's first-order scattering theory. The splittings obtained in this fashion are in good agreement with those measured by neutron scattering and EPR. We discuss the absence of the maximum in resistivity with variation of temperature expected from the Kondo sideband (second-order inelastic scattering) mechanism.
