Some Experimental Aspects of the Spectroscopy of the Emission Intensity of Simple Radicals

Abstract

Experimental distributions of rotational line strength have been recently obtained for the first time in weak transitions of diatomic species [Chem. Phys. 165, 201 (1992)]. Contrary to widespread opinion, a very simple apparatus has been sufficient to achieve this goal, but certain attention must be paid to a few specific points. A description is reported, where some experimental requirements, due to the quantitative character of this spectroscopy, are emphasized.
