Phosphorus — FTIR absorption peaks and assignments
These are the characteristic FTIR wavenumbers where Phosphorus 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.

Phosphorus 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.

Spectrumlogica
Een functionele groepstoekenning wordt betrouwbaarder wanneer meerdere verwachte banden samen verschijnen. Gebruik deze pagina om de best ondersteunde pieken te vinden en bevestig vervolgens dat hetzelfde monster een coherent patroon vertoont in plaats van een enkele geïsoleerde hit.
Gebruik in de praktijk
Deze pagina＇s zijn nuttig voor analyse van onbekend materiaal, piekverklaring in rapporten, probleemoplossing voor polymeren en het verifiëren of een kandidaat-materiaalfamilie chemisch aannemelijk is.
Veelgemaakte fouten
- Het gebruiken van één functionele groepspagina als een volledig materiaaloordeel zonder de rest van het spectrum te controleren.
- Ervan uitgaande dat de sterkste band altijd de meest diagnostische is.
- Vergeten dat verwerking, additieven, veroudering en mengsels de verwachte pieken kunnen verschuiven of verbreden.
Advies voor verificatie
Gebruik DSC, GC-MS of TGA wanneer verschillende materiaalfamilies vergelijkbare banden delen of wanneer mengseleffecten de FTIR-toewijzing onzeker maken.
