  • 摘要

    基于电子顺磁共振(EPR)超精细常数As确定键长的新方法和半自洽场d轨道理论，对MgF2:Mn2+光谱和EPR超精细常数作出了统一解释.得到室温下MgF2:Mn2+晶体中杂质中心Mn—F的键长为0.2124±0.0010nm.

     

    Abstract

    The optical luminescence spetrum and electron paramagnetic resonance hyperfine constant of MnF2:Mn2+ are given a unified explaination on the basis of semi-self consistent field d-orbit theory and a new method of determination of bond length from hyperfine constant. The bond length of Mn—F in MnF2:Mn2+ crystal is determined as 0.2124±0.0010nm.
