A Gas Flow Tube for Spectroscopic Studies.
Abstract
A gas flow tube was constructed to allow chemical reaction studies at pressures from 0.1 torr to 30 torr. The tube was designed to allow introduction of oxidants, diluents, or excited gases. A furnace was constructed to produce high temperature vapor in the combustion chamber of the flow tube. The flow tube was characterized by its pumping speed, pressure, throughput, and evaluating Reynold's and Knudsen's numbers at pressures from 0.1 - 20 torr. Two experiments were conducted to verify the flow tube performance. Singlet molecular oxygen was produced in a microwave discharge and reacted with gaseous I2 to yield chemiluminescence from the transition I2(B) yields I2(X). The spectrum was recorded and the bandheads assigned to vibrational transitions predicted by theory. PbO was created by reacting vaporized lead with N2O. The emissions were compared with literature.
