摘要：

The Infrared and Raman spectra of LiClO4/acetone solutions have been investigated from diluted to high concentrations. It was found that the C=O and C-C stretches of acetone were very sensitive to the interaction between Li+ and acetone molecules. Apparent solvation numbers of 1.9 similar to 3.4 for Li+ have been inferred at different molalities of LiClO4 and the carbonyl group was suggested to be the main bonding site. The ClO4- bands reveal the evidence for the presence of contact ion pair and its dimer. The association constants of LiClO4 in acetone has been calculated and compared with the data obtained from conductivity measurements.
