Therefore the same or similar functional groups in different molecules will typically absorb within the same, specific frequency ranges. Consequently tables of ... Upon first inspection, a typical infrared spectrum can be visually divided into two regions. The left half, above 2000 cm-1, usually contains relatively few peaks,

Functional Group ... 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.
