The EPR and ENDOR spectra of /sup 237/NpF/sub 6/ molecules dilutely substituted for host molecules in single crystals of UF/sub 6/ at temperatures between 1.2 and 2.1 /sup 0/K have been obtained at microwave frequencies, approx.9.4 and approx.9.7 GHz. Approximate values are given for the parameters in a spin Hamiltonian formalism that describes the measurements. The results are discussed.
