Definition of "thermochemical"



 Can anybody explain what is "thermochemical"? What is the difference
 of it from
 "thermodynamic"? Anywhere I can find official definitions? What is
 thermochemical kinetics as in Prof. S. Benson's book "Thermochemical
 Kinetics:
 Methods for the Estimation of Thermochemical Data and Rate Parameters"?
 Thank you very much.
