The frequencies of 28 lines of the 12CF4 (ν2 + ν4) → ν2 laser have been measured with an accuracy of ±0.2 cm-1 for 12C16O2 pump lines from P(14) to R(24). The CF4 pump and laser transitions have been identified and the band origin and rotational constant of the ν2 level determined to be ν2 = 435.27 ± 0.06 cm-1, B2 = 0.19143 ± 0.00007 cm-1. From these constants the laser frequencies expected from any given pumping frequency can be predicted to within ±0.2 cm-1.
