Hamprecht-Cohen-Tozer-Handy

HCTH Hamprecht. Cohen. Tozer. and Handy GGA exchange-coiTelation functional based on a reoptimization/extension of empirical parameters in B97 and a removal of HF exchange. Now a family of functionals with optimizations over different numbers of test-set molecules, typically denoted HCTH/w where n is the number of molecules in the test set, e.g., HCTH/93, HCTH/120, HCTH/147, and HCTH/407. Hamprecht, F. A., Cohen, A. J., Tozer, D. J., and Handy, N. C. 1998. 7. Chem. Phys., 109, 6264. (Most recent refinement, Boese, A. D., Martin, J. M. L., and Handy, N. C. 2003. 7. Chem. Phys., 119, 3005.)...
