✦ Synopsis

High-resolution Fourier transform spectra of (\mathrm{CD}{3} \mathrm{CCH}) at room temperature and at (195 \mathrm{~K}) have been recorded in the region of the (2 v{9}) band (\left(1225-1285 \mathrm{~cm}^{-1}\right)) at an apodized resolution of (0.004 \mathrm{~cm}^{-1}). Approximately 1000 vibration-rotation transitions in the (P) and (R) branches of (2 r_{9}\left(A_{1}\right)) have been fitted with a standard deviation of (0.00035 \mathrm{~cm}^{-1}). Two vibration-rotation interactions. a Fermi resonance with (\left(v_{9}+2 v_{10}\right)^{ \pm 3}\left(A_{1}\right)), and a weak . (x y)-Coriolis interaction with (\left(\nu_{9}+2 v_{10}\right)^{11}(E)), have been identified and analyzed. The parameters of the (2 \nu_{9}\left(A_{1}\right)) state and some of the those of the interacting states have been determined. c. 1993 Academic Press. Inc
