## Abstract The CH~3~โproton resonances for the 2,4โ and 2,6โisomers of toluene diโisocyanate separate when hexafluorobenzene is used as a solvent. Integration of these absorptions over an expanded sweep scale gives the isomer ratio with an accuracy of ยฑ0.5% over the range normally encountered with
