Терагерцовая спектроскопия водных растворов уксусной кислоты

The comparison of the fingerprint region of infrared and Raman spectra of aqueous solutions of acetic acid at concentrations of 0.3 and 0.8 mole fractions and pure solutions with the calculated data on terahertz spectroscopy was carried out. The molecular dynamics simulation of terahertz spectroscopy of aqueous solutions of acetic acid was presented. Terahertz spectroscopy was shown to be informative when comparing the structural reorganization of water molecules in aqueous solutions of acetic acid. Special attention was paid to the collective dynamics of water molecules depending on the concentration of acetic acid.
