High-pressure absorption microspectroscopy of solutions

该应用需要一个价格适中的两件式设备，作为我们自1992年和2003年以来用于研究的两台精密光谱仪的宝贵配件。(The这些仪器的购买也由NSERC资助。所要求的附件将为我们正在进行的项目提供有力的研究工具，这些项目旨在了解决定分子构建块或新材料的光学特性（例如颜色）的各种分子现象。新的配件将使我们能够研究各种材料吸收或反射不同频率光的方式。此外，我们将能够探测某些外部因素（例如压力）如何影响我们制备的新材料对光的吸收。了解材料在压力下的光学性质如何变化，对于基础科学原因和实际应用都很重要。这种现象被称为压致变色，一系列新的商业应用都是基于材料的这种特性。我们希望购买的新设备将使我们能够研究金属化合物的压致变色特性，这些化合物对外部施加的压力表现出有趣的反应。相对温和的成本，建议的仪器意味着我们可以提供一个强大的新的研究工具，我们的学生在一个有吸引力的价格与价值的比率。

This application requests a modestly-priced, two-piece equipment that will serve as a valuable accessory for two of our sophisticated spectrometers that we use for our research studies since 1992 and 2003. (The purchase of these instruments was also funded by NSERC.) The requested accessories will provide a potent research tool for our on-going projects aimed at understanding a variety of molecular phenomena that determine the optical properties (for example, the colour) of molecular building blocks or new materials. The new accessories will allow us to investigate the way in which various materials absorb or reflect light of different frequency. Moreover, we will be able to probe how certain external factors (for example, pressure) can affect the absorption of light by the new materials we prepare. It is important both for fundamental scientific reasons and practical applications to understand how the optical properties of a material changes when it is placed under pressure. This phenomenon is called piezochromism, and a range of new commercial applications are based on this characteristic of materials. The new equipment we hope to purchase will allow us to study the piezochromic properties of metallic compounds that have shown interesting responses to externally applied pressure. The relatively modest cost of the proposed instrumentation means that we can provide a powerful new research tool to our students at an attractive price-to-value ratio.
