摘要：
The noncoincidence effect of the C=O stretch of acetone and of the O-H stretch of methanol in acetone/methanol mixtures has been Studied as function of the concentration of the two liquids in the mixture at 293 K. The observed convex concentration dependence of the noncoincidence effect both for the C=O stretch and the O-H stretch is in agreement with that obtained for a Stockmayer mixture via Monte Carlo simulation, indicating the occurrence of microscopic inhomogeneities.
