Fitting of the long-time signal decay associated with hydrogen molecules moving in nanopores at various angles ${\theta }_{\mathrm{S}}$ between the normal N to the films and the applied magnetic field ${\overrightarrow{H}}_0$ : a) ${\theta }_{\mathrm{S}}=40°$; b) ${\theta }_{\mathrm{S}}=65°$; c) ${\theta }_{\mathrm{S}}=90°$. Solid red circles are experimental results, solid blue curves are fitting according Eq. (7).
