<div dir="ltr">Hello,<div><br></div><div>I would like to do two configuration SCF (TCSCF) calculations for H2 molecule (as an example). Actually I have wave function which looks like C1|aaBar| -C2|bbBar| where a and b correspond to the bonding and antibonding orbitals. At the long distance TCSCF wave function has equal coefficients for both 20 and 02 CSF, which actually means that the wave function does not have ionic component. Is it possible to tell the program to do TCSCF calculations with equal coefficients for C1 and C2 at any distance, or, in other words, to calculate only the covalent component of the wave function? If this is not possible in the current version of the program (Molpro 2010.1), may be developers can tell me what should I change in the program in order to make this possible (if it is relatively easy)?</div>
<div>I also did not find in the manual how one can print Hamiltonian matrix? Can anybody instruct me how to do this?</div><div><br></div><div>Thank you David</div><div><br></div><div>Below you can find inputs for TCSCF and SA-TCSCF</div>
