 Title: EXPERIMENTAL MAPPING OF THE ABSOLUTE VALUE OF THE ELECTRONIC TRANSITION DIPOLE MOMENT FUNCTION $\mu_{e}(R)$ OF THE $^{7}$Li$_{2}$ $A^{1}\Sigma^{+}_{u}-X^{1}\Sigma^{+}_{g}$ SYSTEM Creators: Qi, P.; Salihoglu, O.; Ahmed, E.; Kotochigova, S.; Huennekens, J.; Lyyra, A. M. Issue Date: 2007 Publisher: Ohio State University Abstract: Continuous wave (CW) triple resonance laser spectroscopy} was used to map the absolute value of the electronic transition dipole moment function $\mu_e(R)$ of the $^{7}$Li$_{2}$ A-X system. In this work, the transition dipole moment matrix elements of specific rovibronic molecular transitions were first determined by fitting the observed Autler-Townes splitting spectra. Then by employing the R-centroid approximation, or a multi-variable fit involving higher moments of R, $\mu_e(R)$ has been determined within a relatively large range of internuclear distance R. Finally, this electronic transition dipole moment function is compared with the ab initio calculations with very good agreement.
