Notes
| 1 | Potential data for the 1Σ+ ground state from total scattering cross-section measurements Neumann and Pauly, 1968; see also Schlier and Vietzke, 1969. Neumann and Pauly, 1968 give also potential parameters for the 3Σ+ excited state (De = 0.031 eV Neumann and Pauly, 1968, re = 6.2 Angstroms Neumann and Pauly, 1968) which arises from the same atomic products 2S + 2S. |

| 3 | From the measured Stark coefficient μo2/B0 = 1.81E-18 cm3 and assuming B0 = 0.0631 cm-1 Dagdigian and Wharton, 1972 obtain μel(v=0) = 4.75 D Dagdigian and Wharton, 1972. |
