Solution density-of-states functions

The cycle is closed in step 4 as Rd(ox) relaxes to Rd(Rd), releasing work Clearly Rd -4ox= ox + Rd- The quantities A and Aqx are the reorganisation energies of Rd and Ox, i.e., the work that must be done to transform the nuclear arrangement in and around equilibrated Rd to that of equilibrated Ox, and vice versa. These two reorganisation energies are not necessarily the same. 

Since and Aqx are usually not known individually (nor can different values be accommodated within classical Marcus theoiy), their symmetrised value

The gaussian form of the solution density-of-states functions is explained in Appendix 4A.
