Title: Permanent dipole moment of LiCs in the ground state

Deiglmayr et al., Phys. Rev. Lett. 101, 133004 (2008)]. Here we report on an experimental determination of the permanent electric dipole moment of deeply bound LiCs molecules. For ${X}^{1}{\ensuremath{\Sigma}}^{+}$, ${v}^{\ensuremath{''}}=2$, and ${v}^{\ensuremath{''}}=3$ we measure values of $\ensuremath{\mu}=5.5(2)$ D and 5.3(2) D, respectively.Read More
