Frequently Asked Questions

What are the FTIR peaks for?

Fourier Transform Infrared (FTIR) has been developed as a tool for the simultaneous determination of organic components, including chemical bond, as well as organic content (e.g., protein, carbohydrate, and lipid). However, until now, there is no further documents for describing the detailed information in the FTIR peaks.

What is the strength of the carbonyl stretching absorption?

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)

What is the C=O group in the IR spectrum?

Carbonyl Stretching Vibrations The C=O group is one of the most easily recognized peaks in an IR spectrum. The change in dipole moment is significant, making this an intense band, and there are few other groups that give rise to absorbances in the 1600-1850 cm-1range.

What is the best IR absorption spectrum for structure determination?

1690 - 1630 (s) 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.
