With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of California in Riverside will acquire an Absorption and Emission Spectrometer. This equipment will enhance research in a number of areas, including optical spectroscopy at high pressure for studies of pressure induced changes in the optical spectra of organic solids and pressure tuned optical dynamics; the characterization of the chemical architecture of carbon-fiber surfaces; fluorescent tags for Schiff base-forming sites in proteins; absorption and fluorescence studies of metalloporphyrins with applications to molecular photonics design; synthesis of inherently fluorescent macrocycles for use as chemical sensors; and photophysics of polymeric squaraines.An optical spectrometer is an essential part of a research active department. For example, routine optical measurements can be used to identify reaction products, evaluate sample purity and/or degradation, photometrically determine concentrations, and measure optical properties of thin films and optical components.

通过化学研究工具和设施（CRIF）计划的奖项，加利福尼亚大学河滨分校的化学系将获得吸收和发射光谱仪。 该设备将增强许多领域的研究，包括在高压下进行压力引起的有机固体光谱变化和压力调谐光学动力学的变化的光谱；碳纤维表面化学结构的表征；蛋白质中的Schiff碱基形成位点的荧光标签；金属卟啉的吸收和荧光研究，应用于分子光子设计；固有的荧光大环的合成作为化学传感器；聚合物方形的光体物理学。光谱仪是研究活动部门的重要组成部分。 例如，常规的光学测量可用于识别反应产物，评估样品纯度和/或降解，光度法确定浓度，并测量薄膜和光学成分的光学性质。
