✦ Synopsis

High-resolution (0:005 cm -1 ) infrared absorption spectra of HCN in the 2 2 band region near 1411 cm -1 have been recorded at room temperature using the Bruker IFS120HR Fourier transform spectrometer located at Paciÿc Northwest National Laboratory. Four spectra of high-purity (99.8%) HCN together with three spectra of lean mixtures (∼ 3%) of HCN in dry air were simultaneously ÿt using a multispectrum nonlinear least-squares procedure. The analysis yielded room temperature values for absolute intensities, self-and air-broadening coe cients, and self-and air-induced pressure shift coe cients for numerous lines in the 2 0 2 band of H 12 C 14 N. In addition, intensities, self-and air-broadening coe cients for several lines of the 3 1 2 -1 2 hot band, as well as intensities for a number of lines in the 2 0 2 band of H 13 C 14 N, were also determined. Since there are no previous measurements of broadening and shift parameters reported in the 2 0 2 band, our results are compared with values recently determined in the 1 band of H 12 C 14 N and with current HITRAN values.
