✦ Synopsis

We have made a precise study of the circular polarisation of rotationally resolved features of laserexcited iodine. The J' = 19,u'=161evelof3~~u was excited using circularly polarised dye-laser fluorescence and a quantitative data on polarisation features representing inelastic transfer of AJ' = 30 was recorded. The experimental circular polarisation ratios were compared to those predicted by two totally conserving models, AM = 0 and A0 = 0. The agreement between experimental potits and the predictions based on the former lead to the formation of a new selection rule on rotationally inelastic transfer namely.
