摘要：

Hydrogen and helium pressure induced broadening and line shifts of the nu(4) band of isotopic methane ((CH4)-C-13) have been measured at room temperature for many lines in the P, Q and R branches. The measurements were obtained using the Im Fourier Transform Spectrometer at the KPNO McMath Solar Telescope with a spectral resolution of 0.0065 cm(-1). Data were obtained for 266 absorption lines for a range of J values up to J = 16; the pressure broadening results are compared to similar measurements made for the common isotope (CH4)-C-12 and a small, but consistent variation is noted.
