摘要：
Two-dimensional correlation infrared (2D IR) spectroscopy method has been used to probe molecular interactions between dimethyl sulfoxide (DMSO) and paraldehyde. Selective interactions are expressed quantitatively by a normalized 2D IR parameter. Correlation coefficient, of the synchronous 2D IR spectrum. It was found that there exists a selective interaction between S=O and the, cyclic tri-hydrogen group in paraldehyde. (C) 2004 Elsevier B.V. All rights reserved.
