“…1 The 1 Values for 7 Li 133 Cs, KRb, and RbCs, obtained with similar methods, were presented previously [14,16]. The values in Table I differ slightly (by around 1% except for some values of eQq) calculations were performed at the equilibrium geometry for each molecule, R e = 2.88Å for LiNa [34], 3.32Å for LiK [35], 3.43Å for LiRb [36], 3.67Å for LiCs [37], 3.45Å for NaK [38], 3.64Å for NaRb [39], 3.85Å for NaCs [40], 4.07Å for KRb [41], 4.28Å for KCs [42], and 4.37Å for RbCs [43]. The values of the permanent dipole moments, not included in Table I, can be found in Ref.…”
