Using both $CO_{2}$ and $N_{2}O$ laser lines we have approximately 80\% coverage of the spectrum from $912-9 cm^{-1}$. The beam is formed in a weak He expansion which results in population in both $v=0$ and $v=1$ of the torsion. This study is aimed at understanding the vibrational interactions in a spectroscopically well-characterized molecule containing an internal methyl rotor. The spectrum is found to be quite dense and extensively perturbed. The possible interactions with the bath states and the coupling strengths will be discussed. en_US dc.format.extent 83378 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE 10$\mu$m SPECTRUM OF ACETALDEHYDE en_US dc.type article en_US
