Electron spin resonance spectral parameters (g factors g_{∥}, g_{⊥} and hyperfine structure constants A_{∥}, A_{⊥}) of a tetragonal V^{4+} centers in MB_4O_7 (M = Zn, Cd) are theoretically investigated by using the perturbation formulae for a 3 d^1 ion in tetragonally compressed octahedra. In these formulae, the contributions to the g factors from the tetragonal distortion, characterized by the tetragonal field parameters D_{s} and D_{t} are taken into account by considering the local structures of the ligand octahedron around the V^{4+} due to the Jahn-Teller effect. Based on the calculations, the ligand octahedra around V^{4+} are suggested to suffer about 5.7% and 4.3% relative compression along C_4 axis for MB_4O_7 glasses with M = Zn and Cd, respectively, and negative signs of the hyperfine structure constants A_{∥} and A_{⊥} for V^{4+} centers in MB_4O_7 glasses were suggested in the discussion.
