Gerdes, O. Dulieu, H. Knöckel, E. Tiemann] In a newly built molecular beam apparatus we have measured permanent electric dipole moments of the B 1 Π and X 1 Σ + states of NaK to test the vibrational dependence of the dipole moment function as predicted by ab initio calculations by Aymar and Dulieu [J. Chem. Phys. 122, 204302 (2005)]. Four vibrational bands were studied, the dipole moment for the B 1 Π decreases from 2.73(2) D for v = 3 to 1.99(2) D for v = 13. The vibrational dependence shows a fairly good agreement with theory, but the absolute values are lower than those from the calculation by 13%. The ground state dipole moment of 2.72(6) confirms the earlier result by Wormsbecher et al. [J. Chem. Phys. 74, 6983 (1981)]. EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg, 2011 Gerdes A.
