IR spectroscopy Flashcards
what will give a strong, broad peak at 3400-3200 on IR spectroscopy
alcohol, phenol, carboxylic acid
what will give a medium double peak at 3550-3000 on IR spectroscopy
primary amines/amides
what will give a medium single peak at 3450-3000 on IR spectroscopy
secondary amines/amides
what differentiates a carboxylic acid from alcohol on IR
Carboxylic acid will have a very broad peak at 3200-2900, a sharp, weak spike at 3600, and a strong spike at 1750-1710
where will alkynes show up on IR
strong sharp peaks at 3300
what will produce medium-sharp peaks at 3100-3000
alkenes, aromatics
what will produce medium-strong peaks at 3000-2850 on IR
alkyl groups
what unique IR configuration is produced by aldehydes
a sharp spike at 2820 with a weak spike at 2720
what will produce a sharp, weak to medium spike on IR at 2260-2150
alkynes and nitriles
what will produce a stong spike at 1810-1790
