    Abstract

    Self-broadening coefficients and line strengths have been measured at room temperature for 30 lines of CH in the P and R branches of the ν + ν band, using a tunable diode laser spectrometer. These lines, ranging from P(22) to R(23), are located in the spectral range 1275-1390 cm. A semiclassical calculation of the line broadenings has been performed considering the main electrostatic interactions and an anisotropic dispersion contribution leading to results in satisfactory agreement with the experimental data.
