Abstract

A theoretical and experimental investigation of the electronic absorption spectra and luminescence spectra of the 4- and 5-nitro derivatives of 1(2H)-isoquinolone was undertaken. It was established that the long-wave absorption band of the investigated nitro derivatives is new in relation to the system of bands in the spectrum of the unsubstituted compound. The difference in the luminescent power of the 4- and 5-nitroisoquinolones is explained. A static mechanism of quenching is adopted on the basis of the experimental data on the quenching of the fluorescence of 5-nitro-1(2H)-isoquinolone by proton donors.
