✦ Synopsis

The source of the continuum from flames containing carbon monoxide and oxygen has been investigated by measuring both the emission intensity and [OH] in the flame gases from rich carbon monoxide-hydrogen-air flames. The concentrations of carbon monoxide are calculated from the water gas equilibrium and those o/ oxygen atoms are calculated from the measured [OH]. It is shown that the light-producing step involves a reaction between a carbon monoxide molecule and an oxygen atom with a rate constant of 27×10 -t9 cm3/molecule sec. In the range of conditions employed the continuum amounts to about 95 per cent of the radiation. It is shown that the rate of decay of radicals is" not much affected by the presence of carbon monoxide and carbon dioxide.
