Экспериментальное значение ν(C=O) KETO скоррелировано с эмпирическими параметрами растворителя, в том числе уравнением Кирквуда–Бауэра–Магата (KBM), количеством акцепторов (ANs), уравнением Свейна, линейными соотношениями энергии сольватации (LSER) и квадратным уравнением. Индуцированные растворителем сдвиги ν(C=O) KETO показывают лучшую корреляцию с LSER, чем с KBM, ANs и уравнением Свейна. Обнаружено, что линейное влияние кислотности донора водородной связи растворителя (Aj) на ν(C=O) KЕТО значительно, в то время как основность акцептора водородной связи (Bj) и эффект взаимодействия Aj и Bj несущественны. Отмечено также, что квадратичные эффекты Aj и Bj незначительны, а линейное влияние параметров LSER (π*, δ, α и β) и эффект взаимодействия π* β на ν(С=О) KETO существенны.</p></abstract><trans-abstract xml:lang="en"><p>The solvent effects on C=O stretching vibrational frequency, ν(C=O), of ketoprofen (KETO) were studied experimentally using attenuated total reflection infrared spectroscopy (ATR-IR). The experimental ν(C=O) of KETO were correlated with empirical solvent parameters, including the Kirkwood–Bauer–Magat (KBM) equation, the acceptor numbers (ANs) of the solvents, the Swain equation, linear solvation energy relationships (LSERs), and the quadratic equation (QE). The solvent-induced ν(C=O) shifts of KETO displayed a better correlation with the LSER equation than with the KBM equation, ANs of the solvents, and the Swain equation. The linear effect of the solvent hydrogen-bond donor acidity (Aj) on ν(C=O) of KETO was found to be highly significant, whereas the hydrogen-bond acceptor basicity (Bj) and the interaction effect of Aj and Bj were not significant. It was also observed that the quadratic effects of Aj and Bj were slightly significant. Additionally, the linear effect of LSER parameters (π*, δ, α , and β) and the interaction effect of π* β on the ν(C=O) of KETO were highly significant.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кетопрофен</kwd><kwd>эффект растворителя</kwd><kwd>уравнение Свейна</kwd><kwd>линейная зависимость энергии сольватации</kwd><kwd>квадратичное уравнение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ketoprofen</kwd><kwd>solvent effect</kwd><kwd>Swain equation</kwd><kwd>linear solvation energy relationship</kwd><kwd>quadratic equation</kwd></kwd-group><funding-group><funding-statement xml:lang="en">.
