The temperature dependence of the resistivity of single-crystal K[sub 3]C[sub 60] below 260 K of Crespi [ital et] [ital al]. is analyzed utilizing the results of Raman scattering. It is found that coupling to the two lowest intramolecular [ital H][sub [ital g]] modes gives an excellent fit to the temperature variation of the resistivity with the inclusion of weak lower frequency acoustic or librational scattering. The relative coupling strength of [ital H][sub [ital g]](1) to [ital H][sub [ital g]](2) is found to be similar to that estimated from Raman studies of thin films. The weaker low-frequency contribution is found to have a value consistent with neutron-scattering studies.
