A method is presented for the theoretical calculation of the logarithmic volume derivatives of the three superconducting state parameters, the phonon interaction parameter, the coulomb pseudopotential, and the energy renormalization parameter. The two representative cases of lead and aluminium have been studied. The initial linear drop of T c when plotted against change in volume, which is experimentally observed fact, is theoretically confirmed.
