红外光谱的特征性很强,是鉴别物质结构的有力手段。早期的红外光谱计算机检索系统大多以ASTM穿孔卡片为数据源,但这类数据只含主要峰的波长信息,不含强度信息,且需要在较大型计算机上运行,不便于推广应用。近年来已有人研究以谱线编码为数据 The characteristic of infrared spectrum is very strong, which is a powerful means to identify the structure of matter. Most of the early computerized IR retrieval systems used ASTM punched cards as the data source. However, this type of data only contains the wavelength information of the main peak, does not contain the intensity information, and needs to be run on a larger computer, which is not convenient for popularization and application. In recent years, some people have studied spectral line coding as data
