The behavioUr of the xJC spin-lattice relaxation time as a function of temperature is reported for eight quinoline family compounds. For a set of compounds (ln T~ -~) = f(T -1) is linear, for the other set (In T~ -1) = f(T -~) is best represented by two linear straight lines which intercept at a tem
## Abstract FLAXβISIS spatial localization was combined with inversion recovery to enable the measurement of spatially localized __T__~1~ values. This approach was applied to the transmural determination of creatine phosphate longitudinal relaxation times in the canine myocardium. By examining five
The methyl-t3C and the 14N longitudinal relaxation times in acetonitrile, dissolved in a thermotropic liquid crystal are analyzed with a slowly relaxing local structure modeL This model gives rise to a frequency dependent relaxation mechanism which explains the relatively short 14N relaxation time c
