What absorbs at 1095 cm⁻¹ in an FTIR spectrum?
A band near 1095 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 8 cited sources
Possible functional-group assignments
| Functional group | Supporting facts | Cited sources | Top confidence |
|---|---|---|---|
| C-O single bond | 2 | 2 | 0.9 |
| C-S single bond | 1 | 1 | 1.0 |
| Carbonate | 1 | 1 | 0.9 |
| Metal hydroxyl | 1 | 1 | 0.9 |
| Carboxyl (COOH) | 1 | 0 | 0.8 |
Ranking reflects accumulated literature evidence, not a single authoritative rule. Always confirm against your sample context.
