Proton Zcoman-and dipolar spin-lattice rekxation times and second moments have been measured in polycrystallinc SiH4 at 24 %IHz, between 90 and 3 K. Down to 25 K the classical model for molecular motion appibs; below 25 EC, quantum effects have to be taken into account.
## Recentty. the absolute values of the H and 19F spio-rot~~on constants in SiH4 , GeH C&F4 wore reported on the basis of n;<4ecular beam measurements. We note here a me 4r; CFQ, SiF4, afd od of determinmg the signs of the spin-rotation constants. Our results show that the proton spin-rotation co
