13C and 18O isotope enrichment by vibrational energy exchange pumping of CO
- 1. Calspan Corporation, Advanced Technology Center, Buffalo, New York 14225
Description
Measurements of preferential vibration-to-vibration (V--V) pumping of high vibrational states of 13C 16O and 12C 18O in optically excited CO gas are reported. It is found that the v = 22, 25, 27, 30, and 32 states of 13C 16O and the v = 8, 10, and 12 states of 12C 18O are substantially overpopulated compared to the same states in 12C 16O in strongly V--V pumped CO. Such mixtures are observed to react, forming products enriched in 13C. The results are in reasonable agreement with an analytical kinetic model of V--V pumping in binary mixtures of diatomic gases
