1 Ιαν 2000 · Amino acid side chains play fundamental roles in stabilising protein structures and in catalysing enzymatic reactions. These fields are increasingly investigated by infrared spectroscopy at the molecular level. To help the interpretation of the spectra, a review of the infrared absorption of amino acid side chains in H 2 O and 2 H 2 O is given

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 molecular bonds and functional groups. [1][2] In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify c...

analytical techniques for protein secondary structure analysis. Protein sample forms suitable for FTIR analysis include l. ophilized powders, water solution, and colloids, to name a few. We report herein two examples of protein secondary struct. re determination using transmission FTIR and ATR, respectively. Both methods are fast, consume a .
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 peaks do not overlap) but also an estimation of which types. Amide N-H Stretch: 3700 - 3500 (m)
