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.

根据化学研究仪器和设施（CRIF）计划的授予，加州大学河滨分校化学系将获得一台吸收和发射光谱仪。该设备将加强许多领域的研究，包括高压下的光谱学，用于研究有机固体光谱的压力引起的变化和压力调谐光学动力学；碳纤维表面化学结构的表征蛋白质中希夫碱基形成位点的荧光标记；金属卟啉的吸收和荧光研究及其在分子光子学设计中的应用化学传感器用固有荧光大环的合成以及聚合物方烷的光物理学。光谱仪是科研活动部门必不可少的组成部分。例如，常规光学测量可用于鉴定反应产物，评估样品纯度和/或降解，光度法测定浓度，以及测量薄膜和光学元件的光学性质。
