| Outline of Final Research Achievements |
The metastable nitrogen molecule N2(A3Σ+u) plays an important role to reaction process with the active species in air pollutants. In particular, N2(A3Σ+u)which contributes to the decomposition of the air pollutant gases is the main radicals. With their long lifetime and high internal energies, N2(A3Σ+u) can decomposc air pollutant gas molecules by excitation transfer reactions.
In this investigation, the determination of the effective lifetime of N2(A3Σ+u) in N2/p-xylene (C8H10), N2/ethyl acetate (C4H8O2), N2/styrene (C8H8), N2/ perfluorocarbon (C2F6 and C3F8), N2/ethane (C2H6), N2/propane (C3H8) and N2/water vapor (H2O) is carried out by waveform analysis in the Townsend discharge region. The collisional quenching rate coefficients of N2(A3Σ+u)by those gases are determined.
Furthermore, we determine the collisional quenching rate coefficients of the metastable excited state of neon Ne(3P2) by the ground state of neon Ne(1S0).
