摘要近红外（NIR）和中红外（mid-IR）光谱由于其灵敏度和多功能性而成为聚合物分析中极其重要的技术。近红外光谱和中红外光谱之间的基本区别在于，中红外区域（400-4000 cm−1）中的谱带主要是由于分子的基本振动，而近红外区域（800-2500 nm）中的吸收主要是由于OH、NH和CH官能团的泛音和组合谱带。由于近红外光谱的最新进展，近红外光谱在化学分析中得到了更广泛的应用。中红外也被更广泛地应用于诸如在线或在线分析和定量分析的应用，部分原因是近红外应用的增加以及中红外技术和计算机分析的进步。化学计量学数据评价技术与漫反射光谱测量相结合，允许非破坏性的，多组分的分析和身份控制的固体聚合物具有不同的形态。介绍……
Abstract Both near-infrared (NIR) and mid-infrared (mid-IR) spectroscopies are extremely important techniques for polymer analysis because of their sensitivity and versatility. The basic difference between NIR and mid-IR spectroscopies is that bands in the mid-IR region, 400–4000 cm−1, are primarily due to molecular fundamental vibrations, and absorptions in the NIR region, 800–2500 nm, are primarily due to overtone and combination bands of OH, NH, and CH functionalities. NIR lately has seen much wider application to chemical analysis due to recent advances. Mid-IR is also being more widely applied for applications such as at- or on-line analysis and quantitative analysis, due partly to the increased NIR applications and advances in mid-IR technique and computer analysis. Chemometric data evaluation techniques in combination with diffuse reflection spectroscopic measurements have allowed nondestructive, multicomponent analysis and identity control of solid polymers with varying morphologies. The introduct...
