โฆ Synopsis
The isotropic and anisotropic proton hypertine tensors in malonic and glutaconic acid radicals have been calculated from first principles, using the spin-polarized discrete variational Xa method (DVM). The calculated values are found to be in good agreement ( 5 20%) with the results of ESR and ENDOR experiments. The sensitivity of the hypertine Constants to molecular conformation has been examined by calculations at several different geometries.
