Abstract

The internuclear dependence of the CO (A ¹π-X¹ Σ⁺) transition moment has been obtained for the range 1.0 <r̄ < 1.8 Å. This was done by making laser induced fluorescence measurements on highly vibrationally excited CO. These data were jointly fit with fluorescence lifetime data from a previous study done by Field et al. The second-order fit obtained was 〈R_e(r̄)〉 = 10.57(41)[1 - 1.177(22)r̄+0.350(13)r̄²] D. This fit provides a good description of the transition moment function in that it quantitatively fits the fluorescence branching ratio data and lifetime data and agrees with the qualitative observation of CO(A-X) transition strengths.
