Nuclear Magnetic Resonance in D2

Nuclear Magnetic Resonance in D2

A study of the NMR absorption in solid D2 in both hcp and cubic phase is reported. The molefraction C of para molecules (i.e. those with a rotational angular momentum J=1) ranged from 0.93 to 0.02, and the temperature was varied between 0.5 and 10 K. In the hcp phase, second moments M2 were obtained...

Zusammenfassung:A study of the NMR absorption in solid D2 in both hcp and cubic phase is reported. The molefraction C of para molecules (i.e. those with a rotational angular momentum J=1) ranged from 0.93 to 0.02, and the temperature was varied between 0.5 and 10 K. In the hcp phase, second moments M2 were obtained from the analysis of both c.w. and pulse experiments. In the cubic phase, where the lineshape has two doublets, an analysis in terms of the orientational order parameter is performed. (Author)
