By simulating the electron paramagnetic resonance(EPR)and optical spectra on the basis of the 120×120 complete energy matrix,this paper determines the local lattice structure parameters R1 and R2 for MCl:V2+(M=Na,K,Rb)systems at 77 K,195 K and RT(room temperature 295 K or 302 K),respectively.The theoretical results indicate that there exists a compressed distortion in MCl:V2+ systems.Meanwhile,it finds that the structure parameters R1,R2 and|△R|(=R1-R2)increase with the rising temperature.Subsequently,from the analysis it concludes that the relation of EPR parameter D vs.△R is approximately linear.Finally,the effects of orbital reduction factor k on the g factors for the three systems have been discussed.
