Purchase of a Luminescence Spectrometer

这个来自化学研究仪器项目的奖项将帮助三一大学化学系获得一个发光光谱仪，以支持该本科机构的化学研究和教育项目。此次收购将加强的化学研究领域包括：1)四吡啶和胆红素类似物的光物理性质；2)由荧光蒽衍生的立体受阻取代多环芳烃。发光光谱仪将是该部门仪器能力的重要补充，极大地加强了当前和未来处理电子激发态发射的研究工作。发光是在分子激发态衰变过程中发生的光发射，如果立即发生称为荧光，如果在激发态形成后很长一段时间发生称为磷光。发光光谱是一种非常灵敏的工具，用于测量极低浓度的生物分子和研究光化学反应的动力学和机制。

This award from the Chemistry Research Instrumentation Program will help the Department of Chemistry at Trinity University acquire a luminescence spectrometer to support the research and education programs in chemistry at this undergraduate institution. Among the areas of chemical research that will be enhanced by this acquisition are 1) photophysical properties of tetrapyrroles and bilirubin analogs, and 2) sterically hindered substituted polycyclic aromatic hydrocarbons derived from fluoranthene. The luminescence spectrometer will be a significant addition to the department's instrumentation capabilities, greatly enhancing current and future research efforts dealing with emission from electronically excited states. Luminescence is light emission which occurs during the decay of an excited state of a molecule, and is called fluorescence if it occurs immediately or phosphorescence if it occurs a long time after the formation of the excited state. Luminescence spectroscopy is a very sensitive tool for measuring very low concentrations of biomolecules and in studying kinetics and mechanisms of photochemical reactions.
