Low density polyethylene was spin-labelled with an oxazolidine-N-oxyl group. Correlation times for the motion of the label were calculated both in the slow-motion region and in the motionallynarrowed region. In the latter situation, the central line shape was successfully simulated. A correlation ma

The relaxation properties of a spin system weakly coupled to lattice degrees of freedom are described using an equation of motion for the spin density matrix. This equation is derived using a general weak coupling theory which has been previously developed. To second order in the weak coupling para
The standard theories of spin relaxation have not sufficiently emphasised the connection of this phenomenon to other linear irreversible processes and the role of entropy production has also not been clearly discussed. In order to contribute to this problem, we start here with the linear relation b
