Dear Alexei,
Unfortunately I don't know about them. I right now wish to know how should I resolve this state flipping. Please tell me how to do it from the output file with state tracking on.

Kind Regards,

>>>Dear Users,
>>>I need your help regarding the state flipping in TDDFT calculations. I switch on the state tracing feature in S1 optimization. As far as I have read there is possibility of excited states getting mixed up or flipped. But I really don't know how to figure out this  state flipping and determine the correct order of states. Somebody please help me in understanding this.
