They are crossing at around -0.5 Angstroms. If the data is adiabatic they should not cross(i.e there should be an avoided crossing).But these seems diabatic.<br><br>Can any one please help me in this. Please excuse me if I understood the concept of adiabatic - <span>daibatic</span> surfaces wrongly. <br><br>Thank you <br><br><div style="text-align: left;"><div style="text-align: right;"><span style="font-style:
