Abstract
The increase in fluorescence yield of β‐naphthylamine vapors in the presence of foreign gases provides a new powerful method for studying energy exchange. The effect, discovered by Neporent, is analyzed kinetically and the analog of the Stern‐Volmer equation for this effect is derived. Neporent's data are recalculated in the light of this analysis. Fluorescence stabilization by deuterium and sulfur hexafluoride is studied experimentally following the procedure of Neporent. It is concluded, in particular, that the vibrational and rotational modes of the hydrogen molecules are inactive in the excitation or de‐excitation of vibrational energy of complex molecules.Keywords
