摘要: The equation representing the decomposition of phosphine by flash photolysis is shown to be PH 3 → P red + 3/2H 2 . phosphorus produced in form small particles which remain suspended gas phase for several minutes provided that total pressure high enough. variation with time spectra , and has been studied secondary reactions consequent upon are homogeneous. a vibrationally excited state at room temperature, transitions involving levels up v9 = 7 being observed. A mechanism production proposed.
