The synchronous luminescence method was used in qualitative analysis of aromatic fraction of low-temperature tar from hard coal. The spectra obtained by this method are simpler than spectra obtained with the use of conventional emission luminescence method. The synchronous luminescence analysis requires the selection of respective Deltalambda parameter values. This parameter is a constant difference between position of excitation and emission monochromators during measurement. From literature, the Deltalambda parameter value of 23 nm was first used here. The characteristic emission ranges of spectra obtained indicated (by comparison with spectra of standards) degree of condensation of aromatic compounds present in investigated mixtures. It was also possible to identify some individual compounds. However, this identification could be more effective with the use of the respective value of Deltalambda parameter for each particular component of the mixture. This manner of analysis was used here, e.g. for investigating aromatic fraction containing phenanthrene (identified previously by gas chromatography method) among other compounds. The spectrum recorded at Deltalambda value characteristic for phenanthrene (53nm) presents a rather simple shape with a maximum at 346 nm attributed to phenanthrene after standard and literature data.
同步发光法用于硬煤低温焦油芳烃馏分的定性分析。该方法获得的光谱比使用传统发射发光法获得的光谱更简单。同步发光分析需要选择相应的Δλ参数值。该参数是测量过程中激发和发射单色仪位置之间的恒定差值。从文献中可知，这里首次使用23nm的Δλ参数值。所得光谱的特征发射范围（通过与标准光谱比较）表明了所研究混合物中存在的芳香族化合物的缩合程度。还能够鉴定出一些个别化合物。然而，对于混合物的每个特定组分使用相应的Δλ参数值，这种鉴定可能会更有效。这里采用了这种分析方式，例如用于研究含有菲（先前通过气相色谱法鉴定）以及其他化合物的芳烃馏分。在菲的特征Δλ值（53nm）下记录的光谱呈现出相当简单的形状，在346nm处有一个最大值，根据标准和文献数据，该最大值归因于菲。
