The fingerprint (200-1800 cm(-1)) region in FT-Raman spectra of Syncrude Sweet Blend (SSB) and its three constituent distillation fractions (naphtha, light gas oil and heavy gas oil) was analyzed in detail in this study. Approximately 50 bands were observed and assigned to functional groups in saturated (alkanes) and unsaturated (aromatics) species. Characteristic bands for mono-, bi-, and tricyclic aromatics were identified and used to quantify these groups in SSB and the distillation fractions. Total aromatics content was determined using the carbon-carbon stretching bands in the 1600-cm(-1) region, and shown to agree with earlier results obtained from the C-H stretching region. The bands due to mono- and bicyclic aromatics permitted calculation of the relative abundances of these species with an accuracy equivalent to that obtained using NMR spectroscopy, a traditional method for measuring this quantity.
本研究详细分析了Syncrude Sweet Blend（SSB）及其三种馏分（石脑油、轻质瓦斯油和重质瓦斯油）的傅里叶变换拉曼光谱中的指纹区（200 - 1800 cm(-1)）。观察到约50条谱带，并将其归属为饱和（烷烃）和不饱和（芳烃）物种中的官能团。鉴定出单环、双环和三环芳烃的特征谱带，并用于定量SSB及其馏分中的这些基团。利用1600 cm(-1)区域的碳 - 碳伸缩谱带测定总芳烃含量，结果表明与先前从C - H伸缩区域获得的结果一致。单环和双环芳烃产生的谱带使得能够计算这些物种的相对丰度，其准确度与使用核磁共振光谱法（一种测量该量的传统方法）所获得的相当。
