Measurements of spectral transmittance in the nu4-fundamental band of (C-12)H4 have been performed at low temperatures using a Fourier transform spectrometer with apodized spectral resolution of 0.06 per cm. With applications to lines formed in the atmospheres of Titan and earth in mind, N2 has been used as the broadening gas. Comparisons of observed and computed spectral transmittances on a line-by-line basis have yielded line strengths, N2-broadened half-widths and their variation with temperature. Best agreement between measured and computed spectra was obtained when the absolute intensity of the band was taken as 128 per (sq cm-atm) at 296 K. Line widths were found to vary as T to the n power with n = -1.0 for lines of the F-species and 0.63 for the A-species. The measured line widths are considerably larger than those used in the AFGL compilation.
