(CC) approach and Moller–Plesset perturbation theory. Accurate predictions have been obtained. Using both methods, the dipole moment has been estimated numerically as energy derivative with respect to an applied electric field at zero field strength. The experimental dipole moment of cis-1-chloro-2-fluoroethylene has been determined by observing the Stark spectrum of the J=40,4←31,3 and J=41,3←40,4
cis-1-chloro-2-fluoroethylene 的平衡几何结构已使用两种不同的从头算方法进行了评估:耦合簇 (CC) 方法和 Moller-Plesset 微扰理论。已经获得了准确的预测。使用这两种方法,偶极矩已在数值上估计为相对于在零场强下施加的电场的能量导数。cis-1-chloro-2-fluoroethylene 的实验偶极矩已通过观察 J=40,4←31,3 和 J=41,3←40,4 跃迁的 Stark 光谱来确定。频谱轮廓已拟合到模型函数,该模型函数计算为超精细斯塔克分量上的洛伦兹轮廓之和,其频率是通过对施加电场的每个值的完整旋转四极斯塔克哈密顿矩阵进行对角化得出的。
