已发表的dmso -n-醇体系的体积混合数据表明，烷基链长度的增加，从吸引相互作用到排斥相互作用的优势转变。通过FTIR测量，研究了这些相互作用相对优势的光谱标记。虽然所研究的醇（C3-C5）的大多数振动模式表现出非常相似的行为，但CO扭转模式显示出最大红移与吸引和排斥平衡之间的强烈相关性。
Published volumetric mixing data for DMSO-n-alcohol systems show a transition from attractive to repulsive interaction dominance for increasing alkyl chain length. A spectroscopic marker for the relative dominance of these interactions is investigated by FTIR measurements. While most vibrational modes show very similar behavior for the alcohols (C3-C5) studied, the CO torsion mode reveals a strong correlation between maximum red-shift and the balance of attraction and repulsion.
