Abstract

In the first part of this paper I show that phonon scattering by modes derived from intermolecular, as well as intramolecular, motion, can explain the magnitude and pressure- and temperature-dependence of the conductivity of (TTF)(TCNQ) from 150 300°K. The scattering includes one and two-phonon processes, the data requiring that the former be predominant. The second part of the paper is devoted to showing that the 2-fold increase in spin susceptibility X from 100 to 3000K is due to lattice expansion. A counteracting change in the density of states due to the self-energy is proposed to explain the flattening and subsequent decrease of X found at higher temperatures.
