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.
## Abstract Transverse nuclear magnetic relaxation and selfβdiffusion of water were measured in hydrated collagen II. Selfβdiffusion measurements were conducted by pulsed field gradient NMR (PFG NMR) and weighting of the different species in the signal by variable __T__~2~ relaxation in the experim
