The available experimental data for ClONO$_2$ have been extended by a new FASSST spectrum recorded between 118-378 GHz at greater sensitivity and resolution than hitherto and on a more pure sample. \vspace{0.2cm} The new spectrum allowed an improvement in the spectroscopic constants for the ground state and $\nu_9$, as well as more confident assignment of rotational transitions in higher vibrational states. Application of the AABS package for $Assignment and Analysis of Broadband Spectra$}}kisiel/prospe.htm} was crucial in keeping track of the transitions already assigned and rapid extension of datasets for new states. The analyses of the relatively isolated $\nu_6$ (435 cm$^{-1}$) and of the $\nu_5$/$\nu_6\nu_9$ dyad (551 cm$^{-1}$) have now been completed for both $^{35}$ClONO$_2$ and $^{37}$ClONO$_2$. In the parent isotopologue the $\nu_5$ and $\nu_6\nu_9$ states are found to be 4.124652(6) cm$^{-1}$ apart and to be connected by a sufficiently strong Coriolis interaction to give rise to measurable interstate transitions and to perturbed hyperfine splitting patterns. en_US dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE ROTATIONAL SPECTRUM OF CHLORINE NITRATE (ClONO$_2$): $\nu_6$ AND THE $\nu_5$/$\nu_6\nu_9$ DYAD en_US dc.type article en_US
