The wavelength of the 3.39‐μm line of methane has been measured with respect to the Kr86 6057‐A standard by using a frequency‐controlled Fabry‐Perot interferometer. We have exhaustively studied systematic offsets inherent in the experiment, including effects due to asymmetry of the Kr standard line. Lacking a convention relating the defined Kr wavelength 6057.802 105 A to observables of the krypton line (e.g., center of gravity or fringe maximum intensity point), we report two methane… CONTINUE READING
