3H NMR of the tritiated isotopologues of methane in nematic liquid-crystal solvents

The NMR spectra of the tritiated isotopologues of methane dissolved in several nematic liquid-crystalline solvents are measured. The spectral parameters obtained agree extremely well with those predicted from earlier NMR studies of the deuterated isotopologues, providing excellent confirmation of the theory for vibration-reorientation interaction developed earlier.
