The method or technique of infrared spectroscopy is conducted with an instrument called an infrared spectrometer (or spectrophotometer) which produces an infrared spectrum.

Infrared Spectroscopy is the analysis of infrared light interacting with a molecule. This can be analyzed in three ways by measuring absorption, emission and reflection.

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 …

The interferometer is the heart of a IR spectrometer and consists of a beam splitter, a stationary mirror, and a moving mirror. The beam splitter is a semi-transparent mirror that splits a collimated beam of …

We briefly explain the fundamentals of infrared (IR) spectroscopy and focus on the basic questions about FT-IR, ATR, transmission and reflection.

An infrared spectrometer is defined as an instrument that collects thermal infrared radiation, splits it into two beams, and measures the resulting interferences to reconstruct the source spectrum using …

Jan 8, 2022 · Infrared spectrometers, similar in principle to other spectrometer, permit chemists to obtain absorption spectra of compounds that are a unique reflection of their molecular structure.

Jan 16, 2026 · Infrared spectroscopy (IR spectroscopy) is an optical technique that detects molecular bond vibrations and rotations upon absorption of infrared light. Because different chemical functional...

Jan 7, 2026 · Spectroscopy - Infrared, Molecular, Analysis: This technique covers the region of the electromagnetic spectrum between the visible (wavelength of 800 nanometres) and the short …
