Spectroscopic and semiempirical investigation of the structural features of hetarylazo-5-isoxazolones tautomerism

3-Methyl-4-hetarylazo-5-isoxazolones (I–IV) have been synthesized and investigated on the basis of Fourier transform infrared (FT-IR), UV–visible (UV–Vis), proton nuclear magnetic resonance (1H NMR) spectroscopic techniques and elemental analysis. The measured FT-IR and 1H NMR spectra together with...
