## Description

 Title: Rotationally-resolved High-resolution Laser Spectroscopy Of The B 2e′← X 2a2′ Transition Of 15no3 Radical Author(s): Tada, Kohei Contributor(s): Hirota, Eizi; Ishiwata, Takashi; Kasahara, Shunji Subject(s): Radicals Abstract: Nitrate radical (NO$_{3}$) has two electronic excited states: $A~^{2}E"$ and $B~^{2}E'$ near the electronic ground state: $X~^{2}A_{2}'$. These three electronic states can vibronically interact each other. Therefore, NO$_{3}$ is one of the great subjects for understanding intramolecular interactions in polyatomic radicals. High-resolution fluorescence excitation spectrum and its magnetic effect of the 662 nm band, which is assigned as the 0 - 0 band of the $B~^{2}E' \leftarrow X~^{2}A_{2}'$ transition, of $^{14}$NO$_{3}$ have been observed.\footnote{K. Tada, W. Kashihara, S. Kasahara, M. Baba, T. Ishiwata, and E. Hirota, The 68th OSU Symposium, WJ04 (2013).} The observed $^{14}$NO$_{3}$ spectrum was too complicated to be analyzed rotationally because of less rotational regularity. In this work, we observed high-resolution fluorescence excitation spectrum of the 662 nm band of $^{15}$NO$_{3}$. The observed region was 15080 - 15103 cm$^{-1}$. We also observed the Zeeman splitting of intense rotational lines for unambiguous rotational assignment. A part of the observed rotational lines was successfully assigned by using ground state combination differences calculated from the reported molecular constants\footnote{R. Fujimori, N. Shimizu, J. Tang, T. Ishiwata, and K. Kawaguchi, J. Mol. Spectrosc., 283, 10 (2013).} and the observed Zeeman patterns. The effective molecular constants of the excited state were determined under the oblate symmetric-top model.
