以日本岛津IR 40 8型红外光谱仪为基础 ,建立了红外光谱计算机检测分析系统 ,实现了对原有实验仪器的改造开发。该系统包括 :在线数据采集分析子系统 ,基团库查询子系统 ,谱图库查询子系统 ,红外谱图模拟解析子系统 ,基团库维护子系统 ,谱图库维护子系统和在线帮助子系统。该系统实现了用计算机进行红外数据采集、红外谱图查询和基团解析等 ,大大提高了谱图解析速度和准确度 Based on Japan Shimadzu IR 40 8 Infrared Spectrometer, the infrared spectrum computer detection and analysis system was established and the original experimental apparatus was reformed and developed. The system includes: online data acquisition and analysis subsystem, group database query subsystem, spectrum library query subsystem, infrared spectroscopy simulation analysis subsystem, group library maintenance subsystem, spectrum library maintenance subsystem and online help subsystem. The system realizes the computer using infrared data acquisition, infrared spectrum query and group analysis, greatly improving the spectral resolution speed and accuracy
