Saturated absorption resonances in a gas 13CH3F at the vibration-rotation transition R(4,3) 0–1 of vibration mode ν3 detected in a probe radiation wave transmission in a presence of unidirectional saturating wave are investigated. The width of saturated absorption resonances is increasing with the growth of saturating radiation intensity. In the limit of strong saturation, the resonance shape differs from Lorentzian one by the sharper decrease in the wings, and the resonance width allows to estimate the dipole transition moment d = 0.045 D in good agreement with literature data for this transition of 13CH3F.
