 Title: ZEEMAN SPLITTING OF THE $A^{1}\Sigma^{+}_{u} - b^{3}\Pi_{u}$ PERTURBED LEVELS OF $^{6}Li_{2}$ Creators: Bernheim, R. A.; Gold, L. P.; Jeng, W. H.; Xie, X. Issue Date: 1986 Abstract: The $^{6}Li_{2} A^{1}\Sigma^{+}_{u} (v=2,J=33)$ level is spin-orbit perturbed by the $b^{3}\Pi_{u} (v=9, F_{1e}, N=32)$ $level. ^{1}$ We have studied the effects of magnetic fields up to 5 kG on these perturbed levels using magnetic rotation spectroscopy and sub-Doppler polarization spectroscopy to observe the zero-field separation, Zeeman splittings, and intensity changes of the $(A^{1}\Sigma^{+}_{u}; b^{3}\Pi_{u}) \leftarrow X^{1}\Sigma_{g}^{+}$ spectra. Different M components were selectively observed with different orientations of the magnetic field relative to the laser polarization.
