The absorption spectrum of the 13CH4 molecule in the 3μ region has been recorded at high resolution. 245 allowed transitions belonging to the ν3 band have been interpreted by using a special iterative procedure based on a set of quasi linear equations. The numerical process is quickly convergent and 15 significant spectroscopic constants have been determined. When these constants are checked by the standard damped least squares method, no noticeable change appears in this refinement calculation. The mean standard deviation between the observed and calculated wavenumbers for the 245 transitions is 0.013 cm-1 and the largest deviation does not exceed 0,043 cm-1. This accuracy is a good check for our assignment.Le spectre d'absorption de la mo...
