Abstract
Chemical shifts, coupling constant, free energy, and free energy of activation for 1,1,2,2-tetrabromofluoroethane have been found to depend on temperature and solvent. The results can be explained qualitatively using the “reaction-field” model. Vapor-phase values for the different thermodynamic and NMR properties of the molecule have been estimated. Theory for calculating NMR spectra of two exchanging AX systems has been presented.
