Aspects on Rotational Cooling of Glyoxal Using Carrier Gases He and Ar

Abstract:

Molecular beam characterization performed for the carrier gases He and Ar reveals particularities in glyoxal fluorescence signal and beam rotational temperature related to the carrier gas. The dependence of the fluorescence signal on stagnation pressure at constant glyoxal partial pressure shows that the signal has a maximum that is higher for He than for Ar. The estimation of the effective nozzle diameter, deff, for different stagnation pressure values, p0, suggests that the decrease of the fluorescence intensity at higher p0 can be attributed, at least in part, to deff. On the other hand, Ar has the higher rotational cooling efficiency. Also the results show that the velocity slip (i.e. the difference between the mean velocities of the species in the binary mixture expansion) between glyoxal and carrier gas is not responsible for the difference in rotational cooling efficiencies of He and Ar.
