Abstract:

Spectra were recorded with the aid of a Fluoromax-P spectrofluorimeter (Horiba Jobin Yvon) using n-octane as the pure standard solvent and the 4.2K fiber optic probe. The dataset reports the spectra for 23 high-molecular weight polycyclic aromatic hydrocarbon standards. Concentrations of standards measured ranged from 2.5 ppb to 2001 ppb. Blanks were run and the data have been corrected based on blank measurements.
