The 1H nuclear magnetic resonance (NMR) spectrum of pyridine contains three signals with the integral intensity ratio of 2:1:2 that correspond to the three chemically different protons in the molecule. Ihe mgbaàmà ndị a sitere na α-protons (ọnọdụ 2 na 6, 8.5 ppm), chemical photography, γ-proton (ọnọdụ 4, 7.5 ppm) and β-protons (ọnọdụ 5 na 3 ppm) na 3 ppm. The analogue signal of pyridine can be detected by the pyridine at a higher density within the spe
