Dear Sriman De,


you have to first choose the occupation keyword in fragment 
calculations in order
to enforce a right higher state of C2; it will give
you a molecule calculated in a spin-restricted manner
(as the ADF normally does), accordingly, at next stage, the 
fragoccupation keyword shall be
applied in final ETS-NOCV calculations,

try to use mu suggestions; in case of any problems feel free to send
your input files;


good luck, greetings, Mariusz
