[UV-spectrophotometry in drug control. 47. Drug substances with chromophores and auxochromes in cyclic and tricyclic systems (benzodiazepine, dibenzoazepine and dibenzodiazepine)]. / UV-Spektrophotometrie in der Arzneimittelkontrolle. 47. Mitteilung: Arzneistoffe mit Chromophoren und Auxochromen in bicyclischen und tricyclischen Systemen (Benzodiazepin, Dibenzoazepin und Dibenzodiazepin.

The results of a systematic examination of the UV/VIS spectra of 10 drug substances with chromophores and auxochromes in bicyclic and tricyclic systems (benzodiazepine, dibenzoazepine and dibenzodiazepine) are described. Influences of substituents and solvents on shifts of the E, K, B and R bands are discussed.
