Introduction: Historical Remarks, molecular substances [1]. Almost all of these substances were found, however, to be non-magnetic except for an effect which was later called molecular dia- magnetism. In 1927, shortly after quantum mechanics had been established, W. Heitler and F. London [2] had a monumental success in applying thi

For the charge-transfer salts described in this monograph, free charge carriers (i) are created by combining a donor molecule D, such as TMTSF, BEDT-TTF (hereafter ET) or their derivatives, with an electron acceptor X. Here D should be an . molecule with a su

As an input for such tight-binding band-structure calculations, the molecular orbitals are usually calculated within the extended-Hückel approxi- mation which uses some empirical molecular parameters [169, 170, 82, 79, 81]. As has been discussed in more detail in [86], the extended-Hücke

This is possible because the electron’s charge and spin can interact with the magnetic field via the Lorentz force-induced orbital motion and the Zeeman interaction, respectively. Such studies, often called . (or .), have greatly
