✦ Synopsis

The infrared spectrum of the (\nu_{9}) and (\nu_{10}) bands in (\mathrm{H}{2} \mathrm{C}={ }^{13} \mathrm{C}=\mathrm{CH}{2}) has been studied at a resolution of 0.003 to (0.004 \mathrm{~cm}^{-1}). The bands interact globally by (z)-Coriolis resonance, and several additional vibrational and Coriolis-type perturbations have been identified in this band system. Spectroscopic constants for the ground state have been obtained from a GSCD analysis. Using a model taking into account rotational (l)-type interactions, global (z)-Coriolis perturbation, local ((x, y))-Coriolis interactions with the (2 \nu_{11}, \nu_{4}), and (\nu_{3}) levels, and local vibrational interactions with (3 \nu_{11}) a set of spectroscopic constants have been obtained for (\nu_{9}) and (\nu_{10}). The analyses also yielded a number of resonance parameters and a few spectroscopic constants for the perturbers. ๔ 1994 Academic Press. Inc.
