A phase-shift method has been used to study the bimolecular and termolecular reactions of HF(~P~) with EiH3. The bimolecular and termolecular rate constants are 3.8 x IO-13 cm3moIecule~1sec-and 1.4 X 1O-3o cm6 molecule-2sec-1, respectively. From the difference between the wavelengths of peak emissio

โฆ Synopsis
A Ufctime of (1.86 *00x)8) x 10-6 aec has been determined from phase-shift massurcmcnfs of the luminescence emitted when the NH3*Hg(3P9) complex dissociates.
The lifetime is independent of tha ommooia pressure. By ollowiqg for the finite lifetime of the complex improved values of the rate constanta for reaction of NH3 with IQ(3P6) have bean obtained.

A modification of the rotating sector method has been used to study the mercury-photosensitized luminescence of ammonia. At low ammonia pressures the intensity of the modulated tilminescence decreases rapidly with increasing frequency of modulation, showing that a slow process must intervene between
