Abstract

A common technique for measuring the difference in energy between the ground state and an excited electronic state is by optical absorption which, of course, gives a measure of this difference, subject to definite restrictions. On the other hand, the process of electron transfer to establish a new ground state at high pressure is a thermal one. As we shall find it useful to relate these processes, it is important to understand their differences. We shall find that in many cases the thermal energy is apparently much smaller than the energy observed optically. We shall show that this is reasonable, and present an approximate relationship between them.
