Bensasson, R.V.; Land, E.J.
Triplet-triplet extinction coefficients via energy transfer.
Trans. Faraday Soc. 67: 1904-15 (1971)

2'-Acetonaphthone
Solvent : Benzene

wave length (nm) at maximum, extinction coefficient = 430, 10500

Triplet state population method: Pulse radiolysis
Extinction coefficient estimation method: Energy transfer
Comments: epsilon relative to benzophenone ketyl radical in cyclohexane (epsilonmax = 3700 L mol–1 cm–1); epsilon obtained from a simultaneous least squares fit of data from several compounds making use of cyclohexane to benzene epsilonmax ratios of 1.83 for naphthalene and 1.45 for anthracene
