<p><span style="font-size: 14pt; font-family: 'andale mono', monospace;"><span style="background-color: #ffffff;">FT-IR（傅里叶变换红外光谱）分析是一种广泛用于鉴定化学物质和研究分子结构的技术。它基于不同化学键和功能团对红外辐射的特异性吸收。</span></span></p> <p style="box-sizing: inherit; margin: 0px 0px 0em; padding: 5px 0px 0px; list-style-type: none; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); letter-spacing: 0px !important;"><span style="font-size: 14pt; font-family: 'andale mono', monospace;"><span style="box-sizing: inherit; margin: 0px; padding: 0px; list-style-type: none; letter-spacing: 0px !important;">一、工作原理</span>：</span></p> <p> </p> <p style="box-sizing: inherit; margin: 0px 0px 0em; padding: 5px 0px 0px; list-style-type: none; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); letter-spacing: 0px !important;"><span style="font-size: 14pt; font-family: 'andale mono', monospace;">1、当分子被红外辐射照射时，它们会吸收特定波长的辐射，从而导致分子内部的化学键振动。吸收的辐射波长与分子内部化学键的类型和环境有关。</span></p> <p> </p> <p style="box-sizing: inherit; margin: 0px 0px 0em; padding: 5px 0px 0px; list-style-type: none; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); letter-spacing: 0px !important;"><span style="font-size: 14pt; font-family: 'andale mono', monospace;">2、FT-IR光谱仪使用干涉仪产生干涉图案，随后通过傅里叶变换将这个干涉图案转化为我们常见的光谱。</span></p> <p style="box-sizing: inherit; margin: 0px 0px 0em; padding: 5px 0px 0px; list-style-type: none; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); letter-spacing: 0px !important;"> </p> <p style="box-sizing: inherit; margin: 0px 0px 0em; padding: 5px 0px 0px; list-style-type: none; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); letter-spacing: 0px !important;"><span style="box-sizing: inherit; margin: 0px; padding: 0px; list-style-type: none;
