What absorbs at 558 cm⁻¹ in an FTIR spectrum?
A band near 558 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
Ateb cyflym
A band near 558 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.

Rhesymeg sbectrwm
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 558 cm⁻¹ is usually not enough for material identification by itself.
Defnydd yn y byd go iawn
Mae＇r math hwn o ymholiad yn gyffredin mewn adnabod polymer, sgrinio plastig anhysbys, datrys problemau QC, dilysu deunydd wedi＇i ailgylchu, ac adolygiad o aseiniad copa wedi＇i gefnogi gan lenyddiaeth.
Camgymeriadau cyffredin
- Trin un band ynysig fel prawf o ddeunydd heb wirio o leiaf un neu ddau gopa cefnogol.
- Anwybyddu gorgyffwrdd: gall grwpiau swyddogaethol lluosog gyfrannu ger yr un rhif ton.
- Hepgor dilysu pan fo ychwanegion, cymysgeddau, ocsideiddio, neu halogiad yn gallu ystumio＇r sbectrwm.
Cyngor dilysu
Pan fo amwysedd yn parhau, dilyswch y rhagdybiaeth gyda DSC, GC-MS, neu TGA, yn enwedig ar gyfer cymysgeddau, samplau dirywiedig, a pholymerau llawn.
