Surface tension prediction COSMOTherm

Hello everyone,

I just started using COSMOTherm and Turbomole. I am trying to predict the surface tension of organic molecules, but I am not sure this is feasible in COSMOTherm. I noticed there's an option for predicting the deltaG of transfer, but not surface tension (for liquid-air interface).

Is there anyone who had the same issue? Is it actually possible to predict surface tension or calculate it from the deltaG of transfer?
