Abstract

We measured in function of helium, argon, and oxygen gas pressure, the evolution of the intensities of the fluorescence spectra of YO molecule issuing from a liquid drop of yttrium oxide melted at the focus of a solar furnace. From this evolution and in a simplified approach assuming the independency of the three molecular systems of YO (A2 Π 1/2-X2 Σ +, A2 Π 3/2-X2 Σ +, B2 Σ +-X2 Σ +) we deduced, through the analysis of Stern-Volmer plots, a mean quenching rate coefficients of this molecule in these states by the above mentioned gases.
