The following table lists infrared spectroscopy absorptions by frequency regions.

An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of …

This article will provide a table containing IR spectrum absorbtion frequency values and what they represent.

2023年2月11日 · Table of Common IR Absorptions. Note: strong, medium, weak refers to the length of the peak (in the y axis direction). Note: spectra taken by ATR method (used at …

Table 1. Characteristic IR Absorption Peaks of Functional Groups* * Abbreviations: s = strong; m = medium; w = weak; br = broad; sat. = saturated; conj. = conjugated ** Alcohols, Esters, …

The carbonyl stretching absorption is one of the strongest IR absorptions, and is very useful in structure determination as one can determine both the number of carbonyl groups (assuming …

IR peaks are not 100% reliable. Peaks tend to be stronger (more intense) when there is a large dipole associated with a vibration in the functional group and weaker in less polar bonds (to …

1100-1300 cm -1 (two bands - distinction to ketones, which do not possess C-O!) The absorptions in this range do not apply only to bonds in organic molecules. IR spectroscopy is useful when …

Table of Characteristic IR Absorptions m=medium, w=weak, s=strong, n=narrow, b=broad, sh=sharp frequency, cm –1 bond functional group 3640–3610 (s, sh) O–H stretch, free …
