Small-signal gin mcasuremcnts have been used IO dctcrminc the decay of excited iodine atoms 1(5'1',,,) after flash pho:olysis of CF$. A rate cocIl'icicnt for the deactivation of iodine by CFJI is obtained.
Thr: mwsurcments confirm that in addition to the photolysis another yet uncspl:iincd pumping process contributes to the population inversion. The method used here is &rcnerally apolicablc to kinetic studies in systems where suitable laser sotuccs arc av;tilab!o.

## An energy transfer laser experunent IS reported m which coumarm I acted as the energy donor and coumarin 31-t as the hsng acceptor At an optunum concentration of lo-' hI for the coumann I and 10m3 hl for the coumarin 314 in methanol, the mL\ture was Xwice as efficient as a laser than cuumarm 31
Excitation of iodine fluorescence with a single mode tunable dye lnser allows extensive observation of features from vibrationally and rotationally transferred states populatti through collisions. We have measured the ckcuhr polarisation of these features and observe a very high degree of polarisati
