Title: A FORBIDDEN BAND IN THE FAR INFRARED SPECTRUM OF $H^{1 3}CNO$

Abstract: The far infrared spectrum of HCNO exhibits a widely spread set of perpendicular transitions in the manifold of the quasilinear bending mode, $\nu_{o}$. and the corbiration manifold $\nu_{4} - n\nu$ where $\nu_{4}$ is the skeletal bending mode. We have analyzed the spectrum of the $^{13}C$ substituted species, and found a Q branch without any P or R branches and a P. R. subband without any Q branch. Neither of these features are observed in the spectrum of the parent species. They have been assigned to the vibrational transitions $(v_{i}v_{a})^{\ell} = (02)^{\prime\prime} (11)^{0*}$ and $(02)^{0*}= (11)^{0*}$ respectively. These transitions are only allowed due to a Conclis interaction between the levels $(02)^{0e}$ and $(10)^{1e}$ which was observed as a relatively weak interaction in the parent species.
