Summary
The electronic absorption spectra of someSchiff bases derived from 3-amino-1,2,4-triazole have been investigated in organic solvents of different polarities. Assignment of the absorption bands, solvent effects, and spectral structure correlations are considered. The fundamental IR bands and the main signals in the1H NMR spectra are assigned and discussed with respect to the effect of substituents on the phenyl ring. A change of the electrical conductance of the compounds with increasing temperature is observed for the solid samples.
Zusammenfassung
Die UV/Vis-Spektren einiger von 3-Amino-1,2,4-triazol abgeleiteterSchiffscher Basen wurden in Lösungsmitteln unterschiedlicher Polarität bezüglich Zuordnung der Banden, Lösungsmitteleffekten und Spektrum-Struktur — Korrelationen untersucht. Die wesentlichen IR- und1H-NMR — Signale wurden zugeordnet und werden mit Substituenteneffekten in Beziehung gesetzt. Im Festzustand zeigen die Proben eine Änderung der elektrischen Leitfähigkeit mit steigender Temperatur.
