傅里叶红外光谱的英文
I. Introduction
conclusionInfrared spectroscopy is a common analytical method ud for studying the chemical properties of a sample. Fourier transform infrared spectroscopy (FTIR), also known as Fourier transform infrared (FTIR) analysis, is a type of infrared spectroscopy that us a Fourier transform to obtain the spectral information. In this article, we will discuss the English terminology ud for FTIR.

4. Absorbance: the logarithm of the ratio of the incident radiation to the transmitted radiation, measured in the FTIR spectrum
5. Peak: a point on the FTIR spectrum that corresponds to a specific vibrational mode of the sample

III. Sample Preparation
Before performing FTIR analysis, the sample must be prepared in the form of a thin film or powder to ensure uniformity of the sample.郑重其事是什么意思
IV. Instrumentation
unavailableFTIR analysis requires a Fourier transform infrared spectrometer, which consists of a source, interferometer, and detector. The sample is placed in the path of the infrared bea
m generated by the source and the transmitted or absorbed radiation is measured by the detector. The interferometer is ud to obtain the interferogram, which is then transformed into the FTIR spectrum.
V. Applications
FTIR is ud in various fields such as chemistry, pharmaceuticals, and material science. It is commonly ud for the identification of unknown compounds, characterization of functional groups, and monitoring of chemical reactions.falling
VI. Conclusion
FTIR analysis is a powerful technique for studying the chemical properties of a sample. Understanding the basic terminology and instrumentation ud in FTIR is esntial for accurate interpretation of the spectral data.
