Optical hole-burning in the ultraviolet spectrum of 3,4,9,10-dibenzpyrene at room temperature

Ultraviolet fluorescence spectra are presented for 3,4-benzpyrene, 1,12-benzeperylene and 3,4,9,10-dibenzpyrene, which were obtained by single-laser, consecutive two-proton excitation. Experiments using two-laser excitation have permitted the study of fluorescence line-narrowing in the spectrum of d...

Summary:Ultraviolet fluorescence spectra are presented for 3,4-benzpyrene, 1,12-benzeperylene and 3,4,9,10-dibenzpyrene, which were obtained by single-laser, consecutive two-proton excitation. Experiments using two-laser excitation have permitted the study of fluorescence line-narrowing in the spectrum of dibenzpyrene at 300 K in hexane solution. These unique observations are interpreted in terms of optical site-selection.
