Abstract

The paper reports preliminary results on the kinetics of the molecular spin conversion in solid methane (CH4) and deuterated methane (CD4), obtained through thermal conductivity measurements in the temperature range 2–10 K.

PACS: 63.20.–e Phonons in crystal lattices;
PACS: 66.70.+f Nonelectronic thermal conduction and heat-pulse propagation in solids; thermal waves.

Key words: organic compounds, nuclear spin conversion rate, thermal conductivity, phonons.
