Attenuated total reflectance - Wikipedia
Attenuated total reflection (ATR) is a sampling technique used in conjunction with infrared spectroscopy which enables samples to be examined directly in the solid or liquid state without further preparation.
一文详解红外衰减全反射（ATR）的原理与应用 - 知乎
2022年11月2日 · 反射光谱包括内反射光谱、镜反射光谱和漫反射光谱，其中以内反射光谱技术(Internal Reflection Spectroscopy) 应用为多。 内反射光谱也叫衰减全反射(ATR)光谱，简称ATR 谱，它以光辐射两种介质的界面发生全内反射为基础。
衰减全反射 - 百度百科
衰减全反射（Attenuated Total Reflection，ATR）：光波入射时，入射面内偏振的单色平面光波在密－疏媒质的界上全反射时，光疏媒质中所形成的迅衰场(见衰减波)量可以被耦合到金属或半导体的表面上而使表面等离激元(SP)或表面极化激元共振激发。
Attenuated Total Reflectance (ATR) - Bruker
Attenuated Total Reflection (ATR) is a measurement technique used in IR spectroscopy, the most common measurement technique used in fact. This is thanks to how easy ATR is to use and the broad range of samples that are possible to analyze with this technique.
Attenuated Total Reflection - an overview | ScienceDirect Topics
Attenuated total reflectance (ATR) is applied to samples where the composition of the surface needs to be measured. It is applied to soft samples such as paper, fur, polymers, and textiles, which can achieve good contact with the crystal used.
The Beginner’s Guide to Attenuated Total Reflectance (ATR)
2023年7月26日 · Attenuated Total Reflectance (ATR) is an optical spectroscopy technique that involves directing light through a high refractive index material at an angle greater than the critical angle, leading to total internal reflection, and enabling analysis of a wide range of samples in direct contact with the ATR crystal.
ATR-FTIR Spectroscopy Basics - METTLER TOLEDO
Attenuated total reflectance (ATR) is a sampling methodology that enables the direct examination of solid or liquid samples without further preparation. It utilizes total internal reflection to generate an evanescent wave that penetrates the sample, providing valuable molecular information.
FT-IR - Introduction to Attenuated Total Reflection (ATR) …
2022年8月4日 · Such spectra are called internal reflection spectra or attenuated total reflection (ATR) spectra. ATR is the most commonly accepted descriptor for this spectral collection technique. It is convent to regard the process as internal reflection and the data as ATR spectra.
The Attenuated Total Reflection Method - ScienceDirect
1997年1月1日 · Attenuated Total Reflection (ATR) is essentially a technique for determining the optical constants of thin-film samples that includes the refractive index and the absorption coefficient. It differs from other better-known procedures—such as ellipsometry and reflectometry, in the respect that ATR probes the sample with an evanescent wave ...
Theory of Attenuated Total Reflectance - JASCO
Attenuated Total Reflectance is a form of absorption spectroscopy with a small, defined path length. One of the key drivers of its adoption by the scientific community is there is normally little to no sample preparation, unlike most FTIR methods
