Transitions up to ${K^{\prime\prime}}_{a} = 5$ and ${J^{\prime\prime}} = 45$ were measured. Although this very weak a-type combination band located at $12612 cm^{-1}$ corresponds to very high internal energy of the molecule (${\sim}2/3$ of the dissociation energy), only local perturbation of the ${K^{\prime\prime}}_{a} = 4$ subband of one isotope $(HO^{37}Cl)$ due to a Fermi-type resonance with a "dark" $3\nu_{1} + 2\nu_{2} + 2\nu_{2}$ state was found. Our estimates based on the observed absorption strength and the sensitivity of the improved version of our spectrometer (ring dye laser) show our ability to record overtone bands up to the dissociation threshold in order to study intramolecular vibrational energy redistribution. The progress in this work will be also reported. en_US dc.format.extent 54178 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title INTRACAVITY LASER ABSORPTION SPECTROSCOPY OF HIGHLY EXCITED VIBRATIONAL STATES OF HOCI APPROACHING DISSOCIATION ENERGY. en_US dc.type article en_US
