What absorbs at 1016 cm⁻¹ in an FTIR spectrum?
A band near 1016 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 | 3 | 3 | 0.9 |
| Silicon-oxygen (Si-O) | 1 | 1 | 0.9 |
| Siloxane (Si-O-Si) | 1 | 1 | 0.9 |
| C=n | 1 | 1 | 0.9 |
| Carbohydrate | 1 | 1 | 0.8 |
| Silicon (Si) | 1 | 1 | 0.7 |
Ranking reflects accumulated literature evidence, not a single authoritative rule. Always confirm against your sample context.
