Abstract
We have prepared a computer program for the determination of the fluorescence expected in a gaseous molecular system subjected to intense continuous radiation in the infrared. The parameters entering in the solution of the ``master” or ``rate” equations include V-V/T transaction probability expressions and the Einstein A and B coefficients. The V-V/T expressions currently being used are modifications of those developed by Donald Rapp. The fluorescence intensities follow from the distribution of energy level populations. Initially we are modeling the irradiation of such gases as $C_{2}H_{4}, O_{3}$, $SO_{2}, NH_{3}$ and $CO_{2}$ by an intense $CO_{2}$ laser source. We are examining the variation of fluorescence intensity as a function of parameters such as gas pressure, temperature, laser power and laser frequency.
