Abstract
This letter reports measurements of the intensity‐dependent transmittance of ethylene near 949 cm−1. The qualitatively different behavior of transmittance for the CO2 laser lines P(12) and P(16), which are nearly symmetrically located on opposite sides of the ground‐state resonance, is described in terms of a 3‐level model with an anharmonic frequency shift in the excited‐state resonance. The results are also compared to the predicted intensity‐dependent transmittance for a 2‐level model.Keywords
