摘要：
To investigate the potential energy surfaces and the coupling between the adiabatic states of SO(2 )molecules, it is necessary to consider the non-adiabatic coupling terms (NACTs), where the Born- Oppenheimer approximation breaks down. In this work, we analyze the conical intersections between 1( 1)A(1 )and 1( 1)B(2) states (the A0 states in Cs symmetry) and 1 (1)A(2 )and 1 B-1(1) states (the A00 states in Cs symme-try) using NACTs and adiabatic-to-diabatic transformation (ADT) angles. Our results confirm reasonable interaction between 1 (1)A(1) and 1 B-1(2) states and strong interaction between 1 (1)A(2) and 1 (1)B(1 )states.
