The activation of hydrogen by excited mercury atoms

Abstract
That mercury atoms excited by absorption of the line 2537Å are able to activate various kinds of atoms by collisions of the second kind has been shown in several different ways. Using pressure measurements to follow the reaction, Cario and Franck (1) showed that hydrogen, in the presence of excited mercury vapor, can be activated and made to reduce copper oxide or tungsten oxide, while Dickinson (2) repeated the experiment using gaseous oxygen instead of solid oxide. Employing spectroscopic methods of detection, Cario (3) activated thallium vapor by collisions with excited mercury atoms and observed the radiation of the green thallium line 5351 Å and indeed all the thallium lines which would theoretically be expected.
