The behaviour of 10 new substances with benzene, pyridine and chinoline chromophores was tested in the UV and visible spectral region. Influences of substituents and solvents on shifts of the bands E, K, B and R are discussed.

The results of a systematic examination of the spectra of 34 drugs with dibenzo-p-thiazine chromophores in the ultraviolet and visible range were evaluated. The substances under study were subdivided into 10 different types corresponding to a different substitution in position 3 and in one case in position 5 of the phenothiazine ring system. All of these types are characterized by the bands E, K and B which are--with only a few exceptions--separated by well developed absorption minima.
