Study of the quenching of O2 (1[Sigma]+g) Lakusta, Helen
Abstract
A study of the quenching abilities of a series of compounds containing heavy atoms was undertaken to ascertain whether or not 0₂(¹Σ⁺[formula omitted]) quenching is subject to heavy atom enhancement. Presence of a heavy atom effect would suggest significant quenching via the 0₂(¹Σ⁺[formula omitted] → ³Σˉ[formula omitted]) transition. The fact that no such effect is observed supports the generally assumed quenching mode: 0₂(¹Σ⁺[formula omitted] → ¹Δ[formula omitted]). A systematic investigation of the use of overlap of absorption spectrum of quencher with emission spectrum of 0₂(¹Σ⁺[formula omitted]) to obtain calculated quenching rate constants was undertaken. The correlation between calculated and experimental rate constants are examined and shortcomings of the method are presented.

containing heavy atoms was undertaken to ascertain whether or not
0₂(¹Σ⁺[formula omitted]) quenching is subject to heavy atom enhancement. Presence of a
heavy atom effect would suggest significant quenching via the 0₂(¹Σ⁺[formula omitted] → ³Σˉ[formula omitted]) transition. The fact that no such effect is observed supports
the generally assumed quenching mode: 0₂(¹Σ⁺[formula omitted] → ¹Δ[formula omitted]).
A systematic investigation of the use of overlap of absorption spectrum of quencher with emission spectrum of 0₂(¹Σ⁺[formula omitted]) to obtain calculated quenching rate constants was undertaken. The correlation between calculated and experimental rate constants are examined and shortcomings of the method are presented.
