Sažetak

The 29-orbital one-centre-expansion self-consistent-field; OCE-
SCF, basis for HCP which gave a lower energy than a 71-orbital
basis,2 was used to calculate the electric field gradient, EFG, at the
Cl atom in HCl and in c1-. The 29-orbital basis set1 gave an
' electronic EFG of 3.4942 au, compared to the experimental value3
of 3.4908 au. Calculations on c1- showed that the 71-orbital basis
was badly chosen for the second electron shell. The effect of the
basis on the 4cr and 5cr MO's is discussed, and the qelec is analysed
by orbital-pair type.
