    Research output: Contribution to journalArticlepeer-review


    N-broadening coefficients have been measured for 30 lines of cyanogen chloride (ClCN) at room temperature in the P and R branches of the ν, band, using a tunable diode-laser spectrometer. These lines, with J values ranging from 0 to 55, are located in the spectral range 694-736 cm. The collisional widths are obtained by fitting the spectral lines with a Voigt and a Rautian profile. The broadenings coefficients of ClCN-N have also been calculated from a semiclassical theory involving the atom-atom Lennard-Jones model for the intermolecular potential in addition to electrostatic interaction.
