摘要: The light and heavy liquid water (H2O–D2O) mixtures in the 0–1 molar fraction were studied mid-infrared by Fourier transform infrared attenuated total reflectance (FTIR-ATR) spectroscopy. Five principal factors retrieved factor analysis (FA). When D2O is mixed with H2O, HDO formed because of hopping nature proton (H or D) results three types molecules equilibrium. Because nearest-neighbor interactions, give rise to nine species. Some species evolve concomitantly other giving five observed. We present spectra these their abundances. calculated probability at different fractions which when concomitant are combined gives observed To appreciate clearly difference between spectra, a Gaussian simulation bands was made. numerous components that make up stretch bands, they not ver...
