紫外-可见光谱
UV-Vis spectroscopyUltraviolet-visible spectroscopy is an analytical technique that measures the absorption of light in the ultraviolet and visible regions of the electromagnetic spectrum by a sample. It is used to determine the chemical composition and concentration of substances based on their electronic transitions. / 紫外-可见分光光度法是一种分析技术，通过测量样品在紫外和可见光区域的吸光度来确定其化学成分和浓度，基于物质的电子跃迁。
