Abstract
The 700$cm^{-1}$ and 3050$cm^{-1}$ region of benzene seeded in argon is studied using Fourier transform infrared absorption spectroscopy. Using a band contour analysis of the 700$cm^{-1}$ region, the $T_{rot}$ is determined to be $80\pm 15K$. The assignments of the sequence hot band structure in this region is discussed. The $T_{vib}$ is $> 170K$, which indicates a disequilibrium between the rotational and vibrational degree of freedom. In the 3050$cm^{-1}$ region of the jet spectrum, the rotational enevelopes for the three bands which make up the Fermi triad are separated. A band contour analysis, including Coriolis interaction, is used to study each band.
