基态CT复合物的几何结构（供体-受体距离）和缔合常数很大程度上受施加压力的影响，从而提高了反应速率和加合物产率，特别是在CT激发时，但在两种激发模式下，非对映选择性在升高的压力下没有表现出任何实质性变化。
The geometry (donor-acceptor distance) and association constant of the ground-state CT complex were considerably affected by applied pressure, thus enhancing the reaction rate and the adduct yield particularly upon CT excitation, but the diastereoselectivity did not show any substantial change at elevated pressures in both excitation modes.
