I want to make sure that these two atoms are in opposite spins. how can I format the input file to achieve this condition. And also if somebody knows any software which can plot the atomic structure along with the spins direction then please let me know.<br><br>Thanking you in advance.<br><br>Regards<br>Padmaja Patnaik<br>
