Abstract
Wavelength and intensity effects which we have observed in the flash photolysis of acetone are reviewed. Marked nonmonotonic wavelength effects occurred in the different regions investigated (260, 280 and 300 mμ) and serve to emphasize the problem of interpreting any data obtained with unfiltered light. The data at 300 mμ were compared with those obtained with continuous light sources 10^6 fold less intense. A considerable difference occurred in the C_2H_6/CO ratio. To investigate this intensity effect, flash photolyses were made over a wide range of reduced intensities, as low as 10^4 fold less than the maximum one, and the transition intensity region for change in C_2H_6/CO ratio and CO quantum yield was located. This phenomenon illustrates the more general fact that the apparent primary processes observed at typical flash intensities need not be the same as the primary processes found at low intensities
