Dear molpro users,<div><br></div><div>i'm quite new to mcscf calculations with molpro and i need your help.</div><div>I'm trying to do an casscf calculation on an ethyl peroxy radical but i'm quite confused on the selection of the active space.</div>
<div><br></div><div>I will explain better my problem:</div><div>I'm trying to select the active space of my calculation choosing between most 'chemical relevant' orbitals and to do this i made an orbital localization of the rhf orbitals.</div>
<div>My problem is that the localization changes the orbitals energies and as a consequence their order...so my question is: how can i be sure that the orbitals i put in the multi active space are the onces i choose from the localization's result??</div>
<div><br></div><div>Thank you very much for all the informations you can give me...any advice will be very well-appreciated!!!</div><div><br></div><div>Best regards,</div><div><br></div><div>Marco.</div>
