红外光谱扫描矿物流程
英文回答：
Mineral identification using infrared (IR) spectroscopy is a widely used technique in geology and mineralogy. IR spectroscopy measures the absorption or emission of
infrared radiation by a sample, providing information about the molecular structure and chemical composition of the material. The IR spectrum of a mineral is unique and can be used to identify the mineral species, determine its crystal structure, and provide insights into its chemical bonding.
The IR spectrum of a mineral is typically divided into three regions:
The near-IR region (12,500-4,000 cm-1) corresponds to the overtone and combination bands of fundamental vibrations.
The mid-IR region (4,000-400 cm-1) corresponds to the
fundamental vibrations of functional groups and molecular bonds.
The far-IR region (400-10 cm-1) corresponds to the lattice vibrations of the crystal structure.
The mid-IR region is the most commonly used for mineral identification. The absorption bands in this region correspond to the fundamental vibrations of the mineral's crystal lattice and can be used to identify the mineral species, crystal structure, and chemical bonding.
IR spectroscopy can be used to identify a wide variety of minerals, including silicates, carbonates, oxides, sulfates, and phosphates. It is a relatively simple and inexpensive technique that can be used to identify minerals in both the laboratory and the field.

红外光谱扫描矿物流程。

红外光谱扫描技术在矿物鉴定中得到了广泛的应用，主要用于获取物质的分子结构和化学成分信息。

矿物的红外光谱是独一无二的，可以用来确定矿物种类、晶体结构，并深入了解其化学键合。

通常情况下，矿物的红外光谱可以分为三个区域：
近红外区（12,500-4,000 cm-1），对应于基频振动的泛音和组合频带。

中红外区（4,000-400 cm-1），对应于官能团和分子键的基本振动。

远红外区（400-10 cm-1），对应于晶体结构的晶格振动。

其中，中红外区是最常用于矿物鉴定的区域，该区域的吸收峰对应于矿物晶格的基本振动，可用于识别矿物种类、晶体结构和化学键合。

红外光谱扫描可以用来鉴定多种矿物，包括硅酸盐、碳酸盐、氧化物、硫酸盐和磷酸盐。

它是一种简单且廉价的技术，既可用于实验室，也可用于野外进行矿物鉴定。
