本文利用一套光纤传导低温装置和荧光分光光度计偶联 ,探讨了影响Shpol′skii低温荧光光谱的因素 ,考察了各种实验参数对多环芳烃 (PAHs)Shpol′skii光谱的影响 ,获得了多种PAHs的准线性光谱 ,并配合同步荧光技术举例说明了Shpol′skii低温荧光技术的高效鉴别能力。结果表明 。

The factors affecting Shpol′skii fluorescence spectra have been investigated on a spectrofluorimeter coupled with a cryospectral system connected by optical fibres,and quasi-linear spectra were obtained. In combination with the synchronous fluorescence technique,the capability of spectral resolution in Shpol′skii spectra is illustrated.The result indicates that Shpol′skii fluorescence spectra may become a routine analytical tool for PAHs.
