What absorbs at 1359 cm⁻¹ in an FTIR spectrum?
A band near 1359 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
Schnelle Antwort
A band near 1359 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.

Spektrumslogik
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 1359 cm⁻¹ is usually not enough for material identification by itself.
Praktische Anwendung
Diese Art von Abfrage ist üblich bei der Polymeridentifikation, dem Screening unbekannter Kunststoffe, der Fehlersuche in der Qualitätskontrolle, der Verifizierung von Recyclingmaterial und der literaturgestützten Überprüfung der Peakzuordnung.
Häufige Fehler
- Behandlung einer isolierten Bande als Beweis für ein Material, ohne mindestens einen oder zwei unterstützende Peaks zu überprüfen.
- Überlappung ignorieren: Mehrere funktionelle Gruppen können nahe der gleichen Wellenzahl beitragen.
- Überspringen der Validierung, wenn Additive, Mischungen, Oxidation oder Verunreinigungen das Spektrum verfälschen können.
Beratung zur Verifizierung
Wenn weiterhin Mehrdeutigkeit besteht, validieren Sie die Hypothese mit DSC, GC-MS oder TGA, insbesondere bei Mischungen, degradierten Proben und gefüllten Polymeren.
