The temperature dependence of the g-factor in a graphite monocrystal was st
udied by X-band EPR at 90-300 K temperature range. In this paper we propose
a generalisation of McClure equation for the g = g(T)data description whic
h is based on the assumption that cu (mixing coefficient of the pi bond) is
temperature dependent. (C) 2000 Published by Elsevier Science Ltd.
