However, in many cases an isolated state approach, both for the ground and vibronically excited levels, does not produce satisfactory results either because the experimentally obtained parameters of such model are not physically transparent, \textit{67$^{th}$ Molecular Spectroscopy Symposium}, Columbus, 2012}, or the model fails to predict the observed spectrum, \textit{67$^{th}$ Molecular Spectroscopy Symposium}, Columbus, 2012} to the experimental accuracy. To circumvent these problems, we develop, from the molecular symmetry standpoint, an effective coupled state rotational Hamiltonian directly accounting for the interactions within the appropriate subset of the interacting vibronic states. This approach is expected to be useful for the analysis of the rotational level structure of the closely-spaced vibronic levels such as those occurring in the vibrationally excited manifolds of the open-shell molecules. The application of this approach to the spectra of the nitrate radical, NO$_3$, in the Jahn-Teller active $\tilde{A}^2E''$ state, will be discussed. en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title ANALYSIS OF THE ROTATIONALLY-RESOLVED SPECTRA OF THE VIBRONICALLY-ACTIVE MOLECULES en_US dc.type Article en_US dc.type Image en_US dc.type Presentation en_US
