Abstract
A simple NMR system was used for measurement of the o–H2 concentration in the solid phase. It was found that the system must be calibrated, as the integral of the NMR absorption curve is not proportional to the o–H2 concentration, which was suggested earlier. The influence of the quantum diffusion below 4 K and 0.35 o–H2 content on the results is reported.Keywords
