| Abstract: | The ethyl radical was observed in a low-preasure premixed gasoline/oxygen/argon flame by using tunable vacuum ultraviolet photoionization mass spectrometry. The ionization energy(IE) of the ethyl radical was derived to be(8. 24± 0. 02) eV from the photoionization efficiency curve. In addition, a high-level ab initio Gaussian-3 (G3) method was used to calculate the energies of the radical and its cation. The calculated adiabatic ionization potential is 8. 17eV, which is in good agreement with the experimental value. |
