Notes

1 Dagdigian, Cruse, et al., 1974 have measured the following radiative lifetimes: tau(A)= 31 ns, tau(B)= 39 ns, tau(C)= 26 ns.
2Double heads on account of large spin doubling.
3Thermochemical value (mass-spectrometry) Hildenbrand, 1970 in very good agreement with the most recent flame photometric results of Gurvich, Ryabova, et al., 1971, Gurvich, Ryabova, et al., 1973. Jonah and Zare, 1971 place a lower limit to the dissociation energy at 4.29 eV based on their study of the Sr + Cl2 chemiluminescent reaction.
