✦ Synopsis

We report the rotational analysis of six new bands of (\mathrm{CHD}{3}) between 10800 and (17500 \mathrm{~cm}^{-1}) recorded by Intracavity Laser Absorption Spectroscopy. The rotational constants have been obtained for two perpendicular bands centered at 12476.117 and (14990.696 \mathrm{~cm}^{-1}) and four parallel bands at (11266.952 .12232 .547,15795.82). and (15933.577 \mathrm{~cm}^{-1}). A total of 725 lines have been measured and fitted with a typical root mean square deviation on the order of (0.03 \mathrm{~cm}^{-1}). The variation of the rotational constants (B{v}) and (C_{v}) with the vibrational excitation is linear from the fundamentals up to (16000 \mathrm{~cm}^{-1}). The rotation-vibration constants (\alpha^{B}) and (\alpha^{C}) have been obtained and discussed for the (\nu_{1}, \nu_{2}, \nu_{3}), and (\nu_{5}) modes from the whole set of data available in the infrared and visible ranges.
