title: [UV-spectrophotometry in drug control. 39. Spectrophotometric behavior of substances with chromophores and auxochromes in aliphatic chains, in saturated heterocyclics and the heterocyclic compounds: furan, imidazole, thiazole, thiadiazole and oxadiazole].
abstract: The spectra of 22 drug substances with chromophores and auxochromes in the aliphatic chain, in the saturated heterocyclus and in heterocyclic compounds (furan, imidazole, thiazole, thiadiazole and oxadiazole) underwent a systematic investigation and the results obtained were evaluated. Influences of substituents and solvents on shifts of the E, K, B and R bands were discussed.
