Abstract
The SCF potential surface of the ground state for NO~2~ was calculated by using program JAMOL 3. The McLeanβLoewβBerkowitz CGTO's were used as basis functions. One of the two Nο£ΏO distance R is fixed to 2.25 a.u. and the other one r and the ONO angle ΞΈ are varied from 2.25 to 5.0 a.u. and from 0Β° to 180Β°, respectively. The potential surface has the minimum around r = 2.50 a.u. and ΞΈ = 120Β°, where the energy is found to be β203.954 a.u.
