Dear Mohammad<br>
If I remember well the new formulation of open-shell vdwdf has been implemented in the 5.2.1.or 5.3.0 version. I've performed satisfactory<br>
calculations with vdw-df-c09 (but I've not tested vdw-df2-c09) on an open shell molecule. It seems that you are using the 5.2.0 version. You may try<br>
to switch to a newer version.<br>
HTH<br>
Giuseppe<br>
