Infrared (IR) spectroscopy, alternatively referred to as vibrational spectroscopy, is an analytical technique used in chemical and physical sciences. This spectroscopic technique measures how samples ...

Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...

Mid-infrared (MIR) spectroscopy exploits the 2.5–25 µm spectral window in which molecular vibrational and rotational transitions generate distinctive absorption features. By probing these intrinsic ...

The sample preparation before conducting an infrared spectroscopy (IR) study is as critical as the study itself, and the samples which are difficult to dissolve in any IR-transparent solvent are mixed ...
