High-resolution (0.005 cm-1) infrared absorption spectra of HCN in the 2v2 band region near 1411 cm-1 have been recorded at room temperature using the Bruker IFS120HR Fourier transform spectrometer located at Pacific 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 fit using a multispectrum non-linear least-squares procedure. The analysis yielded room temperature values for absolute intensities, self- and air-broadening coefficients, and self- and air-broadening coefficients for numerous lines in the 2v2 band of H13C14N, were also determined. Since there are no previous measurements of broadening and shift parameters reported in the 2v2 band, our results are compared with values recently determined in the v1 band of H13C14N and with current HITRAN values.
