Abstract
The influence of microscopic inhomogeneities in the noncoincidence effect of the C=O stretch of acetone and on the O-H stretch of methanol in acetone/methanol mixtures has been studied as function of the concentration of the ywo liquids in the mixture. The observed convex concentration dependence of the noncoincidence effect of both vibtational bands is in agreement with that obtained for a Stockmayer mixture via Monte Carlo simulations,indicating the occurrence of microscopic inhomogeneities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
