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.

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.

Spektrumlogik
En funktionel gruppetildeling bliver mere pålidelig, når flere forventede bånd optræder sammen. Brug denne side til at finde de stærkest understøttede toppe, og bekræft derefter, at den samme prøve udviser et sammenhængende mønster snarere end et enkelt isoleret hit.
Anvendelse i virkeligheden
Disse sider er nyttige til analyse af ukendte materialer, topforklaring i rapporter, polymerfejlfinding og verifikation af, om en kandidatmaterialefamilie er kemisk plausibel.
Almindelige fejl
- Brug af én funktionel-gruppe-side som en komplet materialebedømmelse uden at kontrollere resten af spektret.
- Antager, at det stærkeste bånd altid er det mest diagnostiske.
- At glemme, at forarbejdning, tilsætningsstoffer, ældning og blandinger kan flytte eller udvide forventede toppe.
Verifikationsrådgivning
Brug DSC, GC-MS eller TGA, når flere materialefamilier deler lignende bånd, eller når blandings-effekter gør FTIR-tildelingen usikker.
