The results of an electron-nuclear double-resonance (ENDOR) study of the VK center (self-trapped hole) in CaF2 and BaF2 are reported. In addition to reporting the ENDOR hyperfine constants, some interesting features of ENDOR spectra due to the glide-reflection symmetry of the fluorite lattice are discussed. Also, the large Ba++ion produces effects on the fluorine hyperfine constants that are not observed in the ENDOR spectra of the VK center in CaF2, LiF, or NaF.
