Koga and Thakkar's reoptimized (9s5p) and (12s7p) Gaussian basis sets for the atoms Li to Ne are contracted to [4s2p] and [7s4p], respectively, and their (4s) and (6s) sets for H and He are contracted to [2s] and [4s], respectively. The basis sets are tested by performing self‐cosistent‐field ( SCF ) geometry optimizations on LiH, BeH 2 , B 2 H 6 , CH 4 , NH 3 , H 2 O, and HF. The equilibrium geometries of hydrogen peroxide and hydrazine are determined at both the SCF and fourth‐order many‐body perturbation theory level. © 1993 John Wiley & Sons, Inc.
