A simple fluorimeter assembled from commercial components and its use for the study and application of the Shpol'skii effect on polynuclear aromatic hydrocarbons (PAHs) in n-alkane matrices at 77 K are described. The correlation between the dimensions and geometries of PAHs and their corresponding Shpol'skii solvents is considered. Analytical figures of merit have been evaluated, and the power of the Shpol'skii technique with a conventional fluorimeter in the direct qualitative and quantitative determination of 11 PAHs in mixture is demonstrated. Comparisons with conventional room-temperature fluorescence and laser-excited Shpol'skii spectrometry are also commented upon.
描述了一种由商用部件组装而成的简易荧光计，及其在77K下用于研究和应用什波列夫斯基效应于正构烷烃基质中的多环芳烃（PAHs）。考虑了多环芳烃的尺寸和几何形状与其相应的什波列夫斯基溶剂之间的相关性。评估了分析性能指标，并证明了什波列夫斯基技术与传统荧光计在直接定性和定量测定混合物中11种多环芳烃方面的能力。还对与传统室温荧光和激光激发什波列夫斯基光谱法的比较进行了评论。
