Infrared Spectral Interpretation

Infrared interpretation must be performed on a high quality spectrum, otherwise, misleading results can be obtained. More often than not, bad sample preparation is the main cause of poor quality IR spectra.

This module will introduce general infrared interpretation concepts to help you with structural elucidation.

Topics include:

Infrared spectral quality
Orbital hybridization
General interpretation concepts
IR frequencies
Alkanes
Alkenes
Alkynes
Aromatic compounds
Alcohols
OH group
Ethers
Amines
Carbonyl frequencies
Aldehydes
Ketones
Carboxylic acid
Esters
Amides
Anhydrides
Acid chlorides
Fermi resonance
Carbonyl stretching frequencies
Nitrogen stretching frequencies
Sulfur stretching frequencies
Phosphorous, boron, and halogen stretching frequencies
Inorganic stretching frequencies
