โœฆ Synopsis


I RAVE eugg&ed elsewhere [l] how the degree of mixing of two fluids on the molecular sc8le (or its converse, the degree of segregation) could be determined by observing the rate of 8 second-order reaction in the mixture. This method gives essentielly the mean square concentmtion of component A in 8 non-homogeneous mixture of A and B. The method to be described here appear9 to be more powerful, in that it will give the a&ml distribution of devistions from the mesn concentration in the mixture..

Dcuterium NMR measurements of the moIecuiar orientational ordering (nematic order) are reported for a reentrant I&txy mixture of some alkanycyanobiphenyl (nOCB) to which small amounts of perdeuterated p-xylene have been added. The results indicate that the degree of orientational order is enhanced a
