What absorbs at 1468 cm⁻¹ in an FTIR spectrum?
A band near 1468 cm⁻¹ can point to several functional groups. Below are the most likely assignments, ranked by how much published evidence supports each — every one traceable to literature (DOI) and cross-validated against our 130,000+ reference spectra and knowledge graph.
Backed by 6 cited sources
Possible functional-group assignments
| Functional group | Supporting facts | Cited sources | Top confidence |
|---|---|---|---|
| Alkyl C-H | 2 | 2 | 1.0 |
| Phosphorus | 1 | 1 | 1.0 |
| N h | 1 | 1 | 0.9 |
| Carboxyl (COOH) | 1 | 1 | 0.8 |
| Methyl | 1 | 0 | 0.9 |
Ranking reflects accumulated literature evidence, not a single authoritative rule. Always confirm against your sample context.
