Abstract
We have measured the Seebeck coefficient of single crystals of the organic charge transfer salts -methylphenazinium-tetracyanoquinodimethane (NMP-TCNQ) and quinolinium- over the temperature range 300-20°K. The results are compared to simple band theory, which is found inadequate. A comparison with recent calculations in the atomic limit of the Hubbard model qualitatively distinguishes NMP as being close to a half-filled Hubbard band and quinolinium close to a quarter-filled Hubbard band.
