The spectral power distributions of the flames produced by a number of pyrotechnic compositions has been examined in the waveband 400 to 1000 nanometers. To do this a rapid scanning Perkin Elmer Model 108 monochromator was modified and operated as a spectroradiometer at 2 1/2 scans per second through the waveband. The spectral power distributions are presented in graphical form together with tabulations of their luminous intensities and chromaticity co-ordinates. There is also a discussion on the probable assignments of line and band structure observed in the spectra to species present in the flame. At these scanning speeds, it was evident from the spectral power distributions that the power radiated by the flame varied in a periodic manner. An attempt has, therefore, been made to relate existing theories of stable and unstable combustion to the processes occurring in pyrotechnic flames.
