The frequencies of 28 lines of the (12)CF(4) (nu(2) + nu(4)) ? nu(2) laser have been measured with an accuracy of +/-0.2 cm(-1) for (12)C(16)O(2) pump lines from P(14) to R(24). The CF(4) pump and laser transitions have been identified and the band origin and rotational constant of the nu(2) level determined to be nu(2) = 435.27 +/- 0.06 cm(-1), B(2) = 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).
