Fluorescence Spectrometric Determination of Nonfluorescent Compounds via Molecular Fragmentation

这项研究是在分析和表面化学的一般领域，以及光谱学的子领域。这项研究涉及作为分析测量工具的激光光解产物的荧光检测的检查。这种方法对于通常不是荧光的分子应该是有用的。具体的研究领域包括1)挥发性金属络合物的碎裂荧光光谱分析(FFS)，2)激光光解-FFS(LP-FFS)中通过光碎裂实现高分析选择性的脉冲超声展开，3)LP-FFS的“遥感”能力的评估，4)相对较大的非挥发性分子的LP-FFS，5)在LP-FFS测量中使用基质分离以提高灵敏度，以及6)FFS作为气相色谱检测器。这项研究考察了使用激光碎裂非荧光分子，然后对碎片进行荧光检测的分析测量的实用性。这种方法允许对通常不是荧光的分子进行荧光检测。

This research is in the general area of analytical and surface chemistry and in the subfield of spectroscopy. This research involves an examination of fluorescence detection of laser photofragmentation products as an analytical measurement tool. Such an approach should be useful for molecules which are normally not fluorescent. Specific areas of study include 1) fragmentation fluorescence spectrometry (FFS) of volatile metal chelates, 2) pulsed supersonic expansion for high analytical selectivity in laser photolysis-FFS (LP-FFS) via photofragmentation, 3) evaluation of the "remote sensing" capabilities of LP-FFS, 4) LP-FFS of relatively large nonvolatile molecules, 5) the utility of matrix isolation for increased sensitivity in LP-FFS measurements, and 6) FFS as a gas chromatographic detector. This research examines the utility of analytical measurements using laser fragmentation of non-fluorescent molecules followed by fluorescence detection of the fragments. Such an approach allows the fluorescence detection of molecules which are normally not fluorescent.
