Relaxatton times in methyl lodlde, methyl brcrmde and acetomtrile were analyzed at various temperatures, using the idiffusion model of molecular reorientation. CoWon tunes derived from Tfs are III reasonable agreement with values c&xlated from the Enskog model. However, calculated reorientation& tim

The individual 13C spin-lattice relaxation times in three molecules of different molecular size -codeine, brucine and reserpine -have been determined. In all three molecules, T, for methine carbons, being part of the isotropically reorientating skeleton, ranges from 0.15 to 0.23 set corresponding to
## Abstract The indirect __ortho__ and __para__ carbonβcarbon coupling constants in benzene were determined utilizing the deuterium isotope effect on the carbon chemical shifts in 1β__d__~1~β and 1,3,5β__d__~3~βbenzene. The measurements gave for __J__(CC, __ortho__) and __J__(CC, __para__) the valu
## Abstract This study is the first report on the multiexponential __T__~2~ relaxation of the ^13^Cβ1 carbon of glycogen. In contrast to __T__~1~ relaxation, which does not display observable multiexponential decay behavior, __T__~2~ relaxation is described by a continuous distribution of __T__~2~
