Solvent effects on infrared spectroscopy of 17β-hydroxy-17-methyl-2-oxa-5α-Androstan-3-one (cas 1224-95-9) in single solvents

Infrared spectroscopy studies of 17β-hydroxy-17-methyl-2-oxa-5α-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 ET(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.
