visible spectophotometry & Spectrophotometry. INTRODUCTION. Absorption Spectrophotometry in the ultraviolet and visible region is one of the most oldest methods used for quantitative analysis and structural elucidation.
第五章 紫外 / 可见光谱法. （ Ultraviolet and visible spectrophotometry,UV/VIS ）. § 5-1 基本原理. 一、理论基础 1. 分子吸收光谱的产生 分子中存在平动能，平动能只是 温度的函数∴平动不存在跃迁. 分子内还存在价电子运动，又有内部原子在其平衡位置的振动和分子绕其核心的转动。因此，分子具有电子能级，转动能级和转动能级。分子吸收光谱也是由于能级之间的跃迁所引起的。 （见图 5-1 ）. 图 5-1 双原子分子的三种能级跃迁示意图.
Spectrophotometry. Electromagnetic Radiation = Light What is Light? Visible light is a particular kind of electromagnetic radiation X-rays, UV, Infrared, Microwaves, and Radio waves are all light forms Light is a form of Energy
SPECTROPHOTOMETRY. Applied Chemistry. Fundamentals of Spectrophotometry. Introduction 1.) Colorimetry An analytical technique in which the concentration of an analyte is measured by its ability to produce or change the color of a solution Changes the solution’s ability to absorb light
