Abstract
We have recorded the $\nu_{4}$ band (Herzberg numbering) of benzene $1, 3, 5 - d3$ using high resolution $(0.0015 cm^{-1})$ Fourier transform infrared spectroscopy. The spectrum was taken with the benzene sample in a temperature stabilized cell $(4^{\circ}C)$, 20 cm in length. The interferometer used a mylar beamsplitter and the spectrum was recorded with a liquid helium-cooled silicon bolometer. For the band we have fit the following preliminary spectroscopic constants: $\nu_{0} = 531.06401(1)cm^{-1},B^{\prime}=0.171542(2)cm^{-1},(C^{\prime} - B^{\prime})-(c^{\prime\prime}-B^{\prime\prime})=3.48(2)\times 10^{-4}cm^{-1},B^{\prime\prime}=0.171842(3)cm^{-1}$. Band centers of the observed sequences of hot bands will be reported.
