Calculation And Analysis Of Ir Spectrum Of 2-Aminopyridine
, 2021 Normal coordinate analysis of 2-aminopyridine (2AP) and ND2-pyridine have been performed in valance force field approximation. 2AP was taken as planar because of the low barrier to amino group inversion. The IR absorption intensities have been calculated

Macedonian Journal of Chemistry and Chemical Engineering, 2008 Infrared and Raman vibrational spectra of magnesium disaccharinate heptahydrate, Mg(sac)2⋅7H2O, in the 4000–380 cm–1 region (for infrared) and 4000–100 cm–1 region (for Raman) were studied. The assignment of the spectra was based on the experimental data
