Notes

1Lambda-type doubling Deltavef = +0.0052J(J+1).
2H0 = +3.0E-10.
3Lambda-type doubling Deltavfe(v=1) = +0.022J(J+1) - .... D1 = 45E-6. Strong perturbations.
4vgeq2 perturbed by G 1Sigma. Deperturbed constants for v=2 in Effantin and d'Incan, 1974.
5Identification uncertain.
6H0 = +7.2E-10.
7Lambda-type doubling Deltavfe = +0.0100J(J+I) - ... .
8He = +6.0E-10.
9H0 ~+2E-10. Perturbations by E 1Sigma; constants in the Table are effective values.
