A collection of Coriolis-allowed bands have been observed in the far infrared spectrum of $H13CNO$, recorded with the Bruker IFS 120 HR and a resolution of $0.003cm-1$. These bands are not detectable at all in the parent species. Each of these bands acquires intensity from the Coriolis resonance between the $(\nu 4,\nu 5)1=(02)0e$ and $(10)1e$ vibrational states. Further Coriolis-induced transitions have been found in the microwave region. The present work is concerned with deriving information from the intensity of the perturbation-allowed transitions.
