摘要
The emission spectra of hydrogen-oxygen and hydrogen-air flames at 0.1-1 atm exhibit a system of bands between 852 and 880 nm, which is assigned to the H2O2 molecule vibrationally excited into the overtone region. This molecule results from the reaction HO2. + HO2. -> H2O2v + O-2. The overtone region also contains bands at 670 and 846 nm, which are assigned to the vibrationally excited HO2. radical. This radical results from the reaction between H and O-2. The HO2. radicals resulting from H-2 or D-2 combustion inhibited by small amounts of propylene are initially in vibrationally excited states. The role of vibrational deactivation is discussed.
