摘要

The Fourier transform Raman and Fourier transform infrared spectra of 2-amino-5-iodopyridine were recorded in the solid phase. The equilibrium geometry, harmonic vibrational frequencies, infrared intensities and Raman scattering activities were calculated by HF and DFT (B3LYP) methods with the 6-31G(d,p) basis set for C, N, H and LANL2DZ pseudopotential for I. The scaled theoretical wavenumbers showed very good agreement with the experimental ones. A detailed interpretation of the infrared and Raman spectra of 2-amino-5-iodopyridine is reported on the basis of the calculated potential energy distribution. The theoretical spectrograms for the IR spectrum of the title molecule have been constructed.
