构建了氟化汞( ²⁰²Hg ¹⁹F)分子 ²Σ_1/2和 ² Π_1/2态的有效自旋转动哈密顿量,并计算了该分子基态的超精细结构及其在外电场中的斯塔克分裂和外磁场中的塞曼分裂。运用一阶微扰理论,计算模拟了g-因子在外电场中的变化。探讨了利用 ²⁰²Hg ¹⁹F分子N=1, J=1/2, F=1, M_F=±1 态测量电子电偶极矩的可能性(N、J、F为角动量量子数)。

The effective spin-rotational Hamiltonians of 2Σ12 and 2Π12 states of mercuric fluoride ( 202Hg 19F) molecule are constructed, and the hyperfine structures, Stark shift in external electric field and Zeeman shift in external magnetic field of ground state are calculated. The variation of the g-factor in external electric field is simulated with the first-order perturbation theory. The possibility of using the N=1, J=1/2, F=1, MF=±1 state of 202Hg 19F molecule to measure the electron electric dipole moment is discussed (N, J and F are quantum number of angular momentum).
