4muel(v=0) = 0.463 D; quadrupole coupling constants Graff, Dagdigian, et al., 1972, for 7Li in disagreement with the value from the magnetic resonance spectrum Brooks, Anderson, et al., 1972. See also Dagdigian, Graff, et al., 1971 [molecular beam electric deflection] and Rosmus and Meyer, 1976 [ab initio calculation, dipole moment function].
5Theoretical calculation of Habitz and Schwarz, 1975, confirmed by the elastic Na+-on-Li scattering data of von Busch, Hormes, et al., 1975. Slightly lower values computed by Oppenheimer, Bottcher, et al., 1972 and Bertoncini, Das, et al., 1970 who give also results for other spectroscopic constants.
