Abstract

The effect of an electron-phonon coupling quadratic in the phonon operators upon the effective electronic mass and the phonon frequency is calculated to second order in perturbation theory. The renormalization effects increase linearly with the temperature, but, for extended molecules, that of the electronic mass might be considerably larger than that of the phonon frequency. The results are discussed in the context of organic metals.
