The cavity-ringdown technique is applied to measure Rayleigh extinctions of Ar, N<sub>2</sub>, and SF<sub>6</sub> in the 560–650-nm region at 294 K. It is shown that experimental and calculated Rayleigh scattering cross sections agree within an experimental uncertainty of 1% (for SF<sub>6</sub>, 3%).
