Styrene — FTIR absorption peaks and assignments
These are the characteristic FTIR wavenumbers where Styrene tends to absorb, compiled from published literature and ranked by supporting evidence. Each assignment is traceable to a source (DOI) and cross-validated against our 130,000+ reference spectra and knowledge graph.

Réponse rapide
Styrene is usually assigned by looking for a recurring cluster of characteristic peaks rather than one exact textbook number. The table below shows where the literature most often places this group in FTIR, ranked by accumulated evidence.

Logique du spectre
Une attribution de groupe fonctionnel devient plus fiable lorsque plusieurs bandes attendues apparaissent ensemble. Utilisez cette page pour trouver les pics les mieux soutenus, puis confirmez que le même échantillon présente un motif cohérent plutôt qu＇un seul hit isolé.
Utilisation réelle
Ces pages sont utiles pour l＇analyse de matériaux inconnus, l＇explication des pics dans les rapports, le dépannage des polymères et la vérification de la plausibilité chimique d＇une famille de matériaux candidate.
Erreurs courantes
- Utiliser une page de groupe fonctionnel comme verdict complet du matériau sans vérifier le reste du spectre.
- En supposant que la bande la plus forte est toujours la plus diagnostique.
- Oublier que le traitement, les additifs, le vieillissement et les mélanges peuvent décaler ou élargir les pics attendus.
Conseil de vérification
Utilisez DSC, GC-MS ou TGA lorsque plusieurs familles de matériaux partagent des bandes similaires ou lorsque les effets de mélange rendent l＇attribution FTIR incertaine.
