Abstract: | The production of atomic iodine in the ground (2Pfrsol|3/2) and electronically excited (2P) states following laser-induced photodissociation of I2 the region 425–498 nm was monitored directly by resonance spectroscopy. The branching ratio for iodine atom formation. R = [I(2P)]/[I(2P)], is above 0.5 in the region 495–498 nm in agreement with the recent observation of laser action on the atomic transition at 1315 nm following photolysis of I2 using a dye laser. The present experiments permitted deconvolution of the I2 continuous absorption spectrum below 498 into contributions from the B3 Πo,u → X 1Σg+ and 1Πtu → X1σg? transitions. |
