The ground state of the Sc2 molecule
Knight, L. B.; Van Zee, R. J.; Weltner, W. The ground state of the Sc2 molecule. Chem. Phys. Lett. 1983, 94, 296-299.
The X-band ESR spectrum of the 45Sc2 molecule was observed in neon and argon matrices at 4 K. Two fine-structure transitions with extensive 45Sc(I = 72) hyperfine structure were analyzed to establish that the ground state of Sc2 is 5Î£. The hyperfine parameters were shown to be in essential agreement with a sÏƒ1 do1 dÏ€2 electronic configuration.
