An EPR spectrometer is used to study the reactions of vibrationally excited deuterium molecules with hydrogen and deuterium atoms. For the first time selective measurements are made of the separate channels for reactions of vibrationally excited D/sub 2/ molecules with H atoms and their temperatures dependence is studied over the interval from 298 to 367 K. An estimate of the total rate constant for loss of a vibrational quantum in the reaction D + D/sub 2/ (v = 1) at 300 K is obtained. The measurements are in good agreement with dynamic calculations.
