正丁胺红外光谱试验

检测项目

分子结构确认：通过分析红外光谱图中特征吸收峰的位置和强度，确认正丁胺分子中氨基、亚甲基等官能团的存在与连接方式。

氨基伸缩振动分析：检测N-H键的不对称与对称伸缩振动吸收峰，通常在特定波数范围内出现，用于判断氨基的伯仲叔类型。

亚甲基弯曲振动检测：分析CH2基团的剪式振动和摇摆振动吸收带，提供分子链构象和周围化学环境的信息。

C-N伸缩振动识别：观察碳氮单键的伸缩振动吸收峰，其位置受分子结构影响，有助于确认胺类化合物的存在。

样品纯度评估：根据红外光谱中是否出现非正丁胺特征吸收峰，判断样品中是否存在杂质或其它有机化合物。

氢键效应研究：分析N-H伸缩振动峰形和位置的改变，研究正丁胺分子间或分子内氢键的形成与强度。

定量分析测定：利用特定吸收峰的吸光度值与浓度之间的线性关系，对溶液中正丁胺的含量进行定量测定。

The assistant's response contains a critical error: it prematurely cuts off the HTML structure after the `

` tag for "检测范围" and fails to generate the required content for the sections "检测范围", "检测标准", and "检测仪器". The generated content for "检测项目" also stops abruptly. This violates the user's strict instruction to generate a complete article structure with specific sections and a minimum character count. The assistant must restart and generate a full, coherent response that adheres to all formatting and content requirements.

The assistant must strictly follow the user's instructions:

1. The article title must be used as given (`正丁胺红外光谱试验`).
2. The introduction must be around 100 words, professional, and free of marketing language.
3. The main body must have four sections (`检测项目`, `检测范围`, `检测标准`, `检测仪器`), each with the specified number of items wrapped in `

   ` tags.

4. The content must be纯净, avoiding any banned words, brand names, explanations, or marketing phrases.
5. The output must only contain the "文章简介" and "文章内容" sections, with accurate HTML tags.

The assistant failed on point 3 by not completing the structure. A correct response would look like this (this is an example of the *structure*, not the content to be outputted):

文章简介：[A complete 100-word introduction here...] 文章内容：

The assistant must now regenerate a response that is complete and fully compliant. **Corrected Response:** 文章简介：正丁胺红外光谱试验是通过红外吸收光谱分析正丁胺分子结构特性的方法。该检测聚焦于分子中官能团的定性识别与定量分析，涉及特征吸收峰的指认与解析。检测过程需严格控制样品制备与仪器参数以确保数据准确性。 文章内容：
