What absorbs at 601 cm⁻¹ in an FTIR spectrum?
A band near 601 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
Réponse rapide
A band near 601 cm⁻¹ is usually interpreted by checking which functional groups repeatedly co-occur there in the literature, then confirming at least one or two additional peaks in the same sample. This page ranks those assignments by accumulated evidence rather than by a single fixed textbook rule.
Attributions possibles de groupes fonctionnels
| Groupe fonctionnel | Faits à l＇appui | Sources citées | Confiance maximale |
|---|---|---|---|
| Phosphate (PO4) | 6 | 6 | 1,0 |
| Metal oxygen | 3 | 3 | 1,0 |
| Phosphorus | 2 | 2 | 1,0 |
| Alkyl C-H | 1 | 1 | 1,0 |
| Carbonate | 1 | 1 | 0,7 |
Le classement reflète les preuves bibliographiques accumulées, et non une règle faisant autorité. Confirmez toujours dans le contexte de votre échantillon.
Matériaux possibles
| Matériel | Pics de support | Groupes chevauchants | Sources citées |
|---|---|---|---|
| TiO2 | 601, 1700, 1093 | Metal oxygen, Alkyl C-H | 1 |
| PVA | 601, 1660, 2930 | Alkyl C-H | 1 |
| hematite | 601, 1030, 469 | Phosphate (PO4), Metal oxygen | 1 |
| kaolinite | 601, 3696, 693 | Metal oxygen, Phosphate (PO4) | 1 |
| apatite | 601, 3053, 1640 | Phosphate (PO4), Phosphorus, Alkyl C-H | 1 |
| ZnO | 601, 1400, 3430 | Metal oxygen, Alkyl C-H | 1 |
Les matériaux sont affichés uniquement lorsque le même ensemble de littérature soutient cette bande et au moins un pic caractéristique supplémentaire.
Logique du spectre
This band becomes meaningful only when read with its neighboring peaks. In practice, analysts first look at the assignments above, then check whether the same sample also shows other peaks expected for the same structural motif. A lone band near 601 cm⁻¹ is usually not enough for material identification by itself.
Utilisation réelle
Ce type de requête est courant dans l＇identification des polymères, le criblage des plastiques inconnus, le dépannage du contrôle qualité, la vérification des matériaux recyclés et l＇examen de l＇attribution des pics appuyée par la littérature.
Erreurs courantes
- Traiter une bande isolée comme preuve d＇un matériau sans vérifier au moins un ou deux pics de support.
- Ignorer le chevauchement : plusieurs groupes fonctionnels peuvent contribuer près du même nombre d＇onde.
- Sauter la validation lorsque des additifs, des mélanges, l＇oxydation ou la contamination peuvent déformer le spectre.
Conseil de vérification
Lorsque l＇ambiguïté persiste, validez l＇hypothèse avec DSC, GC-MS ou TGA, en particulier pour les mélanges, les échantillons dégradés et les polymères chargés.
