描述了一种能够在纳秒时间尺度上快速记录时间分辨发射光谱的装置。该仪器允许在许多聚合物系统中发生的时间依赖性光物理过程的详细研究。该技术已被用来研究激基缔合物在聚苯乙烯和聚（1-乙烯基萘）的二氯甲烷溶液中的形成动力学。在聚（1-乙烯基萘）中观察到受激基缔合物解离的非生物学证据，但该过程在聚苯乙烯溶液中似乎不重要。
An apparatus is described which enables the rapid recording of time-resolved emission spectra on a nanosecond time scale. The instrument permits detailed study of the time-dependent photo-physical processes occurring in many polymer systems. The technique has been used to investigate the kinetics of excimer formation in methylene chloride solutions of polystyrene and poly(1-vinyl-naphthalene). Unambiguous evidence for excimer dissociation is observed in poly(1-vinylnaphthalene) but the process appears unimportant in solutions of polystyrene.
