Computational NMR coupling constants: Shifting and scaling factors for evaluating 1-J(CH)

Optimized shifting and/or scaling factors for calculating one-bond carbon–hydrogen spin–spin coupling constants have been determined for 35 combinations of representative functionals (PBE, B3LYP, B3P86, B97-2 and M06-L) and basis sets (TZVP, HIIIsu3, EPR-III, aug-cc-pVTZ-J, ccJ-pVDZ, ccJ-pVTZ, ccJ-p...
