Description:
The FSGO model is applied to a large group of diatomic molecules of first-row and second-row atoms, namely, Li2, Be2, B2, C2, N2, O2, F2, CO, PN, P2, CS, SiO, LiF, LiCl, NaF, NaCl, LiNa, and Na2. Groups of diatomic molecules of similar assumed bond structure—CO and N2; N2, PN, and P2; CO, CS, and SiO; LiF, LiCl, NaF, and NaCl; Li2, LiNa, and Na2—are compared within each group. All the bond lengths of the previous systems are predicted quantitatively with an average deviation of 7%.
