It will help me in my work. Thanks in advance.

I have two minimum, one planar and one twisted minimum in the excited state.. I have obtained the CAS orbitals for a planar minimum. I want to read the initial CAS orbitals to a twisted structure (from chk). If I want to change the structure abruptly I will have a lot of warning due to the large rotation of orbitals. I am thinking of obtaining the intermediate structures between these two extreme structure by interpolation. Then I can use a multi-step job to damp the orbitals from planar structure to twisted structure step by step for limited number of structures in between. I dont know is there any keywords for example in QST2 to just find the interpolated structures but not optimize the structure. It would be efficient if I can ask for limited number of intermediate structures between my two extreme structures. I think I can get rid of the large orbital rotation warning by using this trick. I would appreciate any suggestion in this regard.
