Abstract :
This Letter analyzed the hydrogen bond between pyridine and propionic acid using Raman and infrared spectra as a function of concentrations. The wavenumber shift and line width change were investigated to analyze the effects of hydrogen bond on the ring breathing mode and the triangle mode of pyridine. Density functional theory (DFT) at the B3LYP/6-31++G (d,p) level was performed on the binary solution. The simulated vibrational Raman spectra obtained the experimentally observed spectral features about the blue-shifted of the ring breathing mode. Furthermore, the effect of the hydrogen bond on Fermi Resonance (FR) was discussed.
