CCL:G: How to calculate the charge and multisiplity of Gaussian 98



Hi
The charge and Multiplicity are  -2 and 1 for [SO4]2-  anion, and my question is: when the calcalated system have two [SO4]2- anions,  what are the Charge and Multiplicity for the two anions system for Gaussian calculation?  Thank you very much!
 
Best wishes
