Solution Properties of Some Iron and Copper Macrocycles.
… dissociation of FePc in pyridine is reported. Magnetic susceptibilities of FePc in pyridine, 2-methylpyridine, 3-methylpyridine, and 4-methylpyridine indicate the formation of a d5 low-spin radical. In DMSO, FePc is diamagnetic. However, a paramagnetism plausibly explained by a d5 high-spin …

Liouville resolvent methods applied to highly correlated systems
… Anderson Lattice. We calculate specific heats, magnetic susceptibilities, thermal averages of physical operators, and energy bands. We demonstrate that the LRM is a viable method for investigating many body problems. For the Falicov-Kimball, an exact calculation of the atomic limit shows no …
