Представлено молекулярно-динамическое моделирование ТГц-спектроскопии водных растворов уксусной кислоты. Показано, что ТГц-спектроскопия информативна при определении структурной реорганизации молекул воды в водных растворах уксусной кислоты. Особое внимание уделено коллективной динамике молекул воды в зависимости от концентрации уксусной кислоты. </p></abstract><trans-abstract xml:lang="en"><p>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. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>молекулярная динамика</kwd><kwd>терагерцовая спектроскопия</kwd><kwd>автокорреляционная функция скорости</kwd><kwd>водный раствор уксусной кислоты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>molecular dynamics</kwd><kwd>terahertz spectroscopy</kwd><kwd>autocorrelation velocity function</kwd><kwd>aqueous solution of acetic acid</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sh.
