Abstract
High rovibrational levels in the $A \ {^{1}} \Sigma^{+}_{u}$ have been observed by cw triple resonance spectroscopy. Population was moved to the $F {^{1}}\Sigma^{+}_{g}$ state via $X \ {^{1}} \Sigma^{+}_{g} \rightarrow A \ {^{1}} \Sigma^{+}_{u} \rightarrow F \ {^{1}} \Sigma^{+}_{g}$ which employed two ring dye lasers. A Ti-Sapphire ring laser then dumped population back to higher levels in the $A \ {^{1}} \Sigma^{+}_{u}$ state. These levels were detected as dips in the collision induced side fluorescence, $2 {^{3}}\Pi_{g} \rightarrow a {^{3}} \Sigma^{+}_{u}$, which was monitored using a filtered PMT. High levels in the $F {^{1}}\Sigma^{+}_{g}$ state have been observed using optical double resonance (OODR). Rovibrational levels have been observed up to and beyond the shelf in this state using a filtered PMT and an ionization detector.
