Formation of ground state ozone on pulse radiolysis of oxygen

摘要: Abstract The rate of formation ground-state ozone ( 1 A ) in the fast electron pulse radiolysis oxygen has been followed using 253.7 nm Hg resonance line, and a monochromator set for 1.1 bandpass. Under these conditions vibrational ground state O 3 is essentially third order with constant 2.64 × 10 -34 cm 6 molec -2 s -1 . It formed direct combination, from collisional quenching vibrationally excited an electronically precursor, probably B 2 ). Computer modeling suggests that latter can decay either to or ozone. Decrease optical density at indicated most disappeared system within 0.2–0.5 sec. This process due diffusion out path as well slow decomposition following absorption monitoring light by
