Abstract: One hundred fifty-six (CH3F)-C-12 overtone absorption lines, comprised between 11 545 and 11 836 cm(-1), have been observed by using a tunable diode laser (TDL) spectrometer. Their intensities range around 10(-26) cm/molecule and have been measured by utilizing commercial AlGaAs/GaAs laser diodes through the wavelength modulation (WM) and the 2nd harmonic (2f) detection techniques. Self-broadening coefficients and line strengths have been measured at room temperature for seven of the strongest transitions, while air-broadening coefficients have been obtained for two lines. In addition, self- and air-collisional shifts have been measured for the 11 564.25 cm(-1) transition. (C) 2013 Elsevier Ltd. All rights reserved.
