[using these parameters as requested] (https://github.com/psi4/psi4/pull/339#issuecomment-209252377)
Turbomole (and TM notation)
-75.97415476252 (VWN3, “as in Gaussian”, meaning RPA fit)
-75.94075271487 (VWN5 “default”)
Gaussian:
-75.9741544303
Agrees well with the VWN3RPA_C and VWN5_C suggestion for psi4.
(more decimals with better grids)
