| Abstract: | A new model based on the concept of local composition has been proposed for the correlation of the NMR chemical shift data. Consequently, the viscosity and NMR chemical shift data were well correlated simultaneously using this model and the early proposed local composition viscosity equation. The resulting average absolute deviations of viscosity and NMR chemical shift are respectively less than 0.0006 mPa@ s and 0.0072, which suggested the reasonability of the proposed model. |
