Investigation on infrared spectra of androsterone in single solvents

The infrared absorption spectra of the androsterone in 19 pure organic solvents have been investigated. The carbonyl stretching vibration frequencies of androsterone observed in the solvents were correlated with the empirical parameters G, Swain parameters (Aj and Bj) and the linear solvation energy relationships (LSER). The applicabilities of different parameters were discussed and the solute–solvent interactions in single solvents were studied in detail. The correlation results indicated that the LSER is optimal for a complete description of solute–solvent interactions while G-values and Swain parameters are unilateral.
