We consider the Hubbard model for electron correlations in solids in the narrow band regime where the intra‐atomic Coulomb repulsion is large compared to the band width. A high temperature perturbation expansion in the band width is performed to lowest order for the grand partition function. This procedure is carried out for both one dimensional systems, of interest for the TCNQ charge transfer salts, and for a three dimensional cubic lattice. Both the specific heat and magnetic susceptibility are computed as a function of temperature and electron density.
