[CP2K-user] [CP2K:19682] SCCS alpha, beta, and gamma values for ionic liquid

[jiaming li]

Hi,

I try to use sccs model to setup 1-Ethyl-3-methylimidazolium bis 
(trifluoromethylsulfonyl)imide as solvent, and I find the experimental 
surface tension value for this compound which is 35.4 mN/m. Based on cp2k 
manual, this should be gamma value. In this case, how can I find the alpha 
and beta values? Does this experimental value also include the dispersion 
and repulsion term so I just need to put zero in alpha and beta term?

(trifluoromethylsulfonyl)imide measurement:
