title: Ionization constants and fluorescence excitation and emission spectra of the isomeric benzo[a]pyrene phenols.
abstract: The acid dissociation constants, for the ground and lowest excited singlet states of the benzo[a]pyrene phenols, are reported, and correlated with current thought on carcinogen activation. The corrected fluorescence excitation and emission spectra of these compounds and their anions are recorded. The shifts caused by ring hydroxylation of the parent compound, and the relative spectral band intensities for each phenol are compared to those of pyrene, in a brief assessment of spectral transition polarization in the phenols.
