Exchange coupling between two similar ions

[sg_epr]

Hi,
I am trying to fit the EPR data for two S = 1 exchange coupled systems, and getting the reasonable good fit. My problem is that the g and D values which I am getting for them are not same. Can I somehow tell EasySpin that two ions are similar and find the best possible fit for same D & g values. Thanks
