 Title: COLLISIONAL TRANSFER OF ROTATIONAL ENERGY IN THE $^{2}B_{1}$ Creators: Hardwick, J. L. Issue Date: 1983 Publisher: Ohio State University Abstract: Electronic state of Nitrogen Dioxide and Improved Vibrational and Rotational Constants for the (0,2,0) and (0,3,0)states Collisional satellite lines have been observed in fluorescence from nitrogen dioxide excited by the 4545\AA line of the argon laser. The $13_{0,13}$ level of the (0,8,0) vibrational level of the $^{2}B_{1}$ electronic state is populated by the laser and undergoes collisional relaxation to the $11_{0,11^{\prime}}, 15_{0,15^{\prime}}$, and $17_{0,17}$ rotational levels of the same vibronic state. These collisionally populated states are identified by their fluorescence to well-known levels of the ground electronic state and by comparison with the absorption spectrum. Collisional satellites are also observed for fluorescence to the $(0,2,0)^{\prime\prime}$ and $(0,3,0)^{\prime\prime}$ states. These transitions, together with unrelaxed fluorescence lines are used to obtain improved band origins and rotational constants for those vibrational states.
