[求助] How to calculate Distortion-Interaction Analysis

大家好：
最近看文献，看到有人算1,3偶极环加成来看反应中的反应物之间的扭曲能和相互作用能，但是我没明白是怎么算的，所以请教各位大虾！谢谢！具体详见附件

“We utilized the distortion/interaction model(14) to understand the origins of the reactivity difference of PFAAs studied experimentally with enamines and strained dipolarophiles. The activation energy (ΔE‡

is dissected into distortion energy (ΔEd‡

and interaction energy (ΔEi‡

. Distortion energy is the energy required to distort each of the reactants into their respective transition state geometries, without allowing the fragments to interact. The interaction energy is the energy of interaction between the distorted cycloaddends. It is often a net stabilizing quantity that results from charge transfer of occupied–vacant orbital interactions, electrostatic interactions, polarization, and closed-shell (steric) repulsions.”
