Abstract
Measurements were made on the emission from the $v^{\prime}=3$ level of the $A^{2}\Sigma^{+}$ state of OH. Fluorescence scans were taken while exciting the 3-0 band with a tunable laser. The OH was generated in the burnt gases of a low pressure flame where collisions are infrequent enough that energy transfer does not complicate the spectra. Transition probabilities were obtained for $v^{\prime\prime}=0$ to $v^{\prime\prime}=5$. Values for the high vibrational levels of the $X^{2}\Pi_{i}$ state are important for determining the behavior of the electronic transition moment at large internuclear separation. LIF measurements are planned on the $v^{\prime}=2$ and 4 levels of the A state.
