Infrared spectroscopy studies of 17beta-hydroxy-17-methyl-2-oxa-5alpha-androstan-3-one (HMOA) in 20 different pure organic solvents were undertaken to investigate the solute-solvent interactions and to correlate solvent properties, such as the KBM equation, the solvent acceptor number (AN), Schleyer's linear free energy equation (G-value), Dimroth and Reichardt's parameter E(T)(30) and Brownstein's parameter S with the frequency shifts of the carbonyl stretching vibration for solute. The result indicated that the KBM relationship is unsuitable to the complicated molecules. These frequencies exhibited a better correlation with the solvent parameters AN and G-value than others.
对17β-羟基-17-甲基-2-氧杂-5α-雄甾烷-3-酮（HMOA）在20种不同纯有机溶剂中的红外光谱进行了研究，以探究溶质 - 溶剂相互作用，并将溶剂性质，如KBM方程、溶剂受体数（AN）、施莱耶尔线性自由能方程（G值）、迪姆罗思和赖夏特参数E(T)(30)以及布朗斯坦参数S与溶质羰基伸缩振动的频率位移相关联。结果表明，KBM关系不适用于复杂分子。这些频率与溶剂参数AN和G值的相关性比与其他参数的相关性更好。
