WebMay 28, 2024 · The quality of the spectrum (when using a pellet) depends on the intimacy of mixing and the reduction of the suspended particles to 2 microns or less. In general, a dilute solution in a nonpolar solvent furnishes the best (i.e., least distorted) spectrum. The water molecule has three fundamental molecular vibrations. The O-H stretching vibrations give rise to absorption bands with band origins at 3657 cm (ν1, 2.734 μm) and 3756 cm (ν3, 2.662 μm) in the gas phase. The asymmetric stretching vibration, of B2 symmetry in the point group C2v is a normal vibration. The H-O-H bending mode origin is at 1595 cm (ν2, 6.269 μm).
