When I used the optimized ground-state structure of the molecule to calculate the nonadiabatic coupling between its T1 and T2 states, an error occurred. What caused this? Thank you for your answer!

Hello liushu645,

The RPA = 2 skips the CIS or TDDFT/TDA so the job cannot find the file of FILE_SET_TMP_RPA_X.
