Abstract : Application of several different experimental techniques (flame-ion mass spectrometry, microwave cavity resonance, electrostatic probe, and absorption spectrophotometry) reveals that addition of chromium to fuel-rich atmospheric-pressure H2/O2/N2 flames seeded with potassium results in formation of Cr-containing negative ions. A reaction scheme, equilibrium constants and enthalpy changes provide a satisfactory quantitative interpretation of the experimental results. (Author)
