Molecular polarizabilities are computed using ab initio SCF wave functions and second‐order perturbation theory with special attention given to the use of a shifted denominator. Rather small basis sets are used, in order to obtain reasonable values at a reduced cost. Results are presented for H 2 , CO, H 2 O, C 2 H 4 , OCS, C 6 H 6 , Cl 2 , Br 2 , I 2 .
