## Synopsis The results of semiselective 'H-nmr inversion recovery experiments on mnicated calf thymus DNA fragments are reported. The measurements were conducted in aqueous solutions containing 85% D20, in order to reduce the dipolar contribution to the observed relaxation rates. In solutions con

✦ Synopsis
The proton spin-lattice rciaxation tirm TI has been measured in a crq'stallinc powder of Ntl&iO,:
temperature to 4°K at Larmor frequencies of 22 and 56 hiHz. At temperatures below 20°K the recovery of the magnetizntion is given by z~ sum of two cxponentials, Three Tl-minima are ohserved, and one of them can bc explained by the large exchange splitting of the weakly hindered NH: ion.

1H NMR spin-lattice relaxation times (T1) of the N-CH3 proton resonances of phosphocreatine (PCr) and creatine (Cr) in water solutions were obtained using the 1,3,3,1 pulse sequence. These T1 values were equivalent to those obtained in D2O and water using either the conventional inversion-recovery e
The goal of this work is to provide regional T(1) and T(2) values at a field strength of 7 T for the normal mouse brain at 6 weeks and 1 year old. A novel segmented snapshot FLASH sequence was used to measure T(1) in the hippocampus, corpus callosum, and the retrosplenial granular (RSG) cortex; T(2)
