摘要

Pulse radiolysis and FT-IR smog chamber experiments were used to investigate the atmospheric fate of C6H5O () radicals. Pulse radiolysis experiments gave σ (C6H5O ()) 235 nm=(3.82±0.48)× 10-17 cm2 molecule-1, k (C6H5O ()+ NO)=(1.88±0.16)× 10-12, and k (C6H5O ()+ NO2)=(2.08±0.15)× 10-12 cm3 molecule-1 s-1 at 296 K in 1000 mbar of SF6 diluent. No discernible reaction of C6H5O () radicals with O2 was observed in smog ...
