What is Molecular Perturbation Model for the Spin–Lattice Coupling Coefficients of ^6^A~1~ States to E ~θ~ Strains about?

## Abstract The proposed perturbation model involves second‐order molecular spin–orbit interactions between the fundamental state ^6^A~1~, and the components of orbital triplets ^4^T~1~ and ^6^T~1~, calculated in symmetry D~2d~ induced by E‐strains. The matrix elements of the molecular spin–orbit interactions are first calculated for the states ^4^T~1~ and ^6^T~1~ defined from multielectronic configurations with three open shells. Then, it is shown that the second‐order molecular spin–orbit perturbation involving these states ^4^T~1~ and ^6^T~1~ is strictly zero if these states are degenerate. Finally, it is shown that the most important contribution is due to the three states ^4^T~1~, defined from multielectronic configurations with two open shells.
