Abstract
The stretching fundamental, $\nu_{3}$ of $CCl_{4}$ at 13 $\mu m$ is difficult to resolve because of the hot-band structure, overlapping due to the natural chlorine isotopic mix, and Fermi resonance with $\nu_{1} + \nu_{4}$. We have recorded spectra of 1% $CC1_{4}$ in argon, expanded through a 12-cm-long slit, with a tunable diode laser and an effective path of $\sim 3$ m through the expansion. At the resulting effective temperature of $\sim 10$K, we observe fully-resolved rovibrational structure of the spherical top $C^{35}Cl_{4}$, the symmetric to $C^{35}Cl_{3}^{37}Cl$, and the asymmetric to $C^{35}C1_{2}^{37}Cl_{2}$, using natural isotopic $CCl_{4}$. These bands have been analyzed, and the spectroscopic and molecular constants will be reported and discussed.
