Infrared spectroscopy - Wikipedia
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms.

2023年1月30日 · Infrared (IR) spectroscopy is one of the most common and widely used spectroscopic techniques. Absorbing groups in the infrared region absorb within a certain wavelength region. The absorption peaks within this region are usually sharper when compared with absorption peaks from the ultraviolet and visible regions.

2022年1月8日 · Infrared Spectroscopy is the analysis of infrared light interacting with a molecule. The portion of the infrared region most useful for analysis of organic compounds have a wavelength range from 2,500 to 16,000 nm, with a corresponding frequency range from 1.9*1013 to 1.2*1014 Hz.
IR Spectroscopy - Principle and Instrumentation of Infrared Spectroscopy
Infrared Spectroscopy generally refers to the analysis of the interaction of a molecule with infrared light. The IR spectroscopy concept can generally be analyzed in three ways: by measuring reflection, emission, and absorption.
13.1.16: How to Interpret An Infrared Spectrum
Infrared spectroscopy is the study of the interaction of infrared light with matter. The fundamental measurement obtained in infrared spectroscopy is an infrared spectrum, which is a plot of measured infrared intensity versus wavelength (or frequency) of light.

2022年7月13日 · Infrared spectroscopy is the measurement of the interaction of IR radiation with compounds. IR region involves the range between region 400-4000 cm -1. IR radiation causes the excitation of molecules from lower to higher vibrational levels. These vibrational levels are associated with closely spaced rotational levels.

Infrared spectrometers, similar in principle to the UV-Visible spectrometer described elsewhere, permit chemists to obtain absorption spectra of compounds that are a unique reflection of their molecular structure. An example of such a spectrum is …
Infrared (IR) spectroscopy is one of the most common spectroscopic techniques used by organic and inorganic chemists. Simply, it is the absorption measurement of different IR frequencies by a sample positioned in the path of an IR beam. The main goal of IR spectroscopic analysis is to determine the chemical functional groups in the sample.
Infrared Spectroscopy (IR) – Triggering molecular vibrations through irradiation with infrared light. Provides mostly information about the presence or absence of certain functional groups. Mass spectrometry – Bombardment of the sample with electrons and …
