Temperature dependence, single-crystal absorption spectrum

The present work deals with soUd CT complexes of phenazines which, in the most favorable cases, include the crystal structure, single-crystal electron spin resonance (epr) data, the temperature dependence of the magnetic susceptibility or of the powder conductivity, and a CT absorption spectrum. We have not pursued complexes that could not be crystallized, nor have we investigated completely similar materials. 

Suzuki, Yokoyama, and Ito (1967) studied the polarized Raman spectrum of single crystals and made definitive assignments on this basis. These authors also studied the temperature dependence of the spectrum between 300 and 400°K. Hadni and co-workers (1969) studied the far infrared absorptions of single naphthalene crystals in polarized light and confirmed thereby the assignments made for two infrared active lattice vibrations by Harada and Shimanouchi (1966) at 98cm i (.4 ) and at 66 cm" (B ). Pawley and Cyvin (1970) have described a lattice dynamical treatment for solid naphthalene including the internal molecular vibrations. They obtained dispersion curves for both external and internal, modes.
