摘要
The infrared and Raman spectra of 3-methyl 4-nitropyridine N-oxide (POM) in its crystalline state and in various saturated solutions were recorded. They were assigned according to previous results for 4-nitropyridine N-oxide (NPO). The hydrogen bonds between a proton of a water or a methanol molecule and the N-oxide group of POM is clearly characterized by the frequency shift of the N-oxide stretching mode upon changing the proton-donor nature of the solvent. However this phenomenon is weaker than in the case of NPO and shows a correspondingly lower mobility of the charge that is transferred between the nitro and the N-oxide groups.
