Room Temperature Absorption Spectra of High-Molecular Weight Polycyclic Aromatic Hydrocarbons

Room temperature absorption spectra of 25 commercially available polycyclic aromatic hydrocarbons with molecular weight 302 (HMW-PAHs). Spectra were collected with a Cary 50 - Varian UV-VIS absorption spectrometer using a 1.5 nm band-pass. HMW-PAHs were dissolved in n-octane at the parts-per-billion concentration level. All spectra are blank subtracted.本数据集收录了25种市售多环芳烃（polycyclic aromatic hydrocarbons, PAHs）的室温吸收光谱，这些物质均为分子量302的高分子量多环芳烃（HMW-PAHs）。光谱采集采用瓦里安（Varian）Cary 50型紫外-可见（ultraviolet-visible, UV-VIS）吸收光谱仪，测试过程中使用1.5 nm的通带宽度。待测HMW-PAHs以十亿分之一（parts-per-billion, ppb）的浓度级别溶解于正辛烷（n-octane）中。所有光谱均已扣除空白背景。
