Abstract:

Spectra were recorded with the aid of a Fluoromax-P spectrofluorimeter (Horiba Jobin Yvon) using n-octane as the pure standard solvent and standard quartz cuvettes. This dataset reports the excitation and emission spectra of 23 high molecular weight (HMW) polycyclic aromatic hydrocarbons (PAHs) measured at room temperature.

Purpose:

Identify characteristics of HMW-PAH standards.

Data Parameters and Units:

column 1 = X is wavelength (nm), column 2 = Y is intensity (cps)

Methods:

File naming convention: example: 15_ppb_DBahP_RT_emission_smoothed_extended.txt, where 15 = concentration value of high molecular weight polycyclic aromatic hydrocarbon standard; ppb = concentration unit (ppb = parts per billion); DBahP = high molecular weight polycyclic aromatic hydrocarbon standard where the following code list was used: DBelP: Dibenzo[e,l]pyrene DBjlF: Dibenzo[j,l]fluoranthene N12aP: Naphtho[1,2-a]pyrene N12bF: Naphtho[1,2-b]fluoranthene DBahP: Dibenzo[a,h]pyrene N12kF: Naphtho[1,2-k]fluoranthene DBafF: Dibenzo[a,f]fluoranthene BbPer: Benzo[b]perylene DBaeF: Dibenzo[a,e]fluoranthene DBaeP: Dibenzo[a,e]pyrene DBaiP: Dibenzo[a,i]pyrene DBakF: Dibenzo[a,k]fluoranthene DBalP: Dibenzo[a,l]pyrene DBbkF: Dibenzo[b,k]fluoranthene DBdemnN: Dibenzo[de,mn]naphthacene N12eP: Naphtho[1,2-e]pyrene N21aP: Naphtho[2,1-a]pyrene N21bF: Naphtho[2,1-b]fluoranthene N23aP: Naphtho[2,3-a]pyrene N23bF: Naphtho[2,3-b]fluoranthene N23eP: Naphtho[2,3-e]pyrene N23jF: Naphtho[2,3-j]fluoranthene N23kF: Naphtho[2,3-k]fluoranthene; emission - spectra type (emission or excitation); smoothed = spectrum was smoothed using a Savitzky-Golay filter; extended = spectrum was acquired for a certain wavelength range but then extended out to 700 nm so that all the spectra end at 700 nm; curvilyextended = like _extended except instead of repeating the last point up to 700 nm, it was additional points added but curving downwards so that there isn’t a straight line at a high intensity; blanksub = spectrum had blank value subtracted from it.
