Diatomic fluorine was reacted in a low pressure flame with selenium atoms, generated by a microwave discharge in argon seeded with Se 2, and the products were trapped in solid argon; new infrared absorptions were found at 677.0 and 680.4 cm-l for 8ยฐSe19F and 76selgF, respectively.

โฆ Synopsis
By means of the reaction of atomic H or D (produced either in a microwave discharge or on a W filament) with cithcr NO2 or 0, or atomic 0, we have prepared and trapped OH and OD radicals In sohd Ar at 12 K. characterized by their infrared absorption lines at 354820 and 26 I610 m-'. resuectivelv. The reasons for these spectral assignments. and for the rejection of the previously pubhshed asstgnments, are discussed.
