The electronic transition moment of the I2 B O<sup> + </sup><sub>u</sub>–X 1Sigma<sup> + </sup><sub>g</sub> system is determined over a range of R-centroid from 2.8–4.6 Å through gain measurements of an optically pumper I2 laser. The technique reported here represents an important new application of optically pumped diatomic lasers allowing accurate determination of relative dipole strength functions from gain measurements. The results are in agreement with the qualitative predictions of Brewer and Tellinghuisen [J. Chem. Phys. 56, 3929 (1972)].

  10. A better arrangement would be to use two Brewster windows mounted such that translation of the I2 laser mode caused by one is compensated for by the other.

  18. For the transitions measured, the R-centroid approximation is quite good to fourth order. For the worst case, (nu[prime] = 43, nu[double-prime] = 84), R-bar = 4.59 Å, and (R-bar)4 (R-bar4) = 12.7 Å4, an error of 2.9%.
