CHEMI-LUMINESCENCE FROM OXIDATION OF INORGANIC HYDRIDES - SPECTRUM OF TEF

The chemiluminescence which results when hydrogen telluride and fluorine are intimately mixed corresponds to an emission spectrum in the region 3900 - 5200 A which appears to result from the previously unobserved TeF radical. The structure of the vibronic bands arising from transitions between **2 PI //i states has been assigned by analogy with the similar SF spectrum. The difference in spin orbit constants for the ground and excited states is calculated.
