Study of electronically excited carbon atoms, C(21D2), by time-resolved atomic absorption at 193·1 nm, (31P °1â†� 21D2). Part 2.—Reactions of C(21D2) with molecules

Abstract

Electronically excited carbon atoms, C(2¹D₂), generated by the pulsed irradiation of carbon suboxide in the vacuum ultra-violet, have been monitored photoelectrically by time-resolved atomic absorption spectroscopy. The decay of this atom in the presence of a number of molecular gases has been investigated, yielding the following second-order rate constants: [graphic omitted] The results are compared with data for C(2³P_J) and C(2¹S₀).
