Chemiluminescence intensities from the ONO gas phase reaction and from luminol 3-aminophthal hydrazide oxidation in the liquid phase have been measured under the same conditions of geometry, optics and detection over the wavelength range 440-530 nm. The measurements show that the rate constant for ONO emission and the luminol chemiluminescence quantum yield lead to monochromator-photomultiplier calibrations which agree to within a factor of 1.09 plus or minus 0.40. The correction factors for refraction and light trapping which have to be considered when comparing liquid to gas phase luminescence intensities are briefly discussed. Author
