Abstract: The vibration-rotation overtone near $9050 cm^{-1}$ was studied using a Fourier transform spectrometer with resolution of $0.01 cm^{-1}$ and photometric precision of 0.02%. Absolute strengths of corresponding R-branch lines in isotopic ally pure samples were measured under identical conditions to minimize systematic errors in relative strengths. Line strengths for $^{13}CH_{4}$ were observed to be smaller than those for $^{12}CH_{4}$ by as much as 40%. (Similar results were found for $2\nu_{3}$ of methane.) The $^{12}C: ^{13}C$ abundance ratios deduced from $3\nu_{3}$ spectra of planetary atmospheres will now require modifications.
