What absorbs at 601 cm⁻¹ in an FTIR spectrum?
A band near 601 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
Snel antwoord
A band near 601 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.
Mogelijke functionele-groeptoewijzingen
| Functionele groep | Ondersteunende feiten | Geciteerde bronnen | Hoogste vertrouwen |
|---|---|---|---|
| Phosphate (PO4) | 6 | 6 | 1,0 |
| Metal oxygen | 3 | 3 | 1,0 |
| Phosphorus | 2 | 2 | 1,0 |
| Alkyl C-H | 1 | 1 | 1,0 |
| Carbonate | 1 | 1 | 0,7 |

Mogelijke materialen
| Materiaal | Ondersteunende pieken | Overlappende groepen | Geciteerde bronnen |
|---|---|---|---|
| TiO2 | 601, 1700, 1093 | Metal oxygen, Alkyl C-H | 1 |
| PVA | 601, 1660, 2930 | Alkyl C-H | 1 |
| hematite | 601, 1030, 469 | Phosphate (PO4), Metal oxygen | 1 |
| kaolinite | 601, 3696, 693 | Metal oxygen, Phosphate (PO4) | 1 |
| apatite | 601, 3053, 1640 | Phosphate (PO4), Phosphorus, Alkyl C-H | 1 |
| ZnO | 601, 1400, 3430 | Metal oxygen, Alkyl C-H | 1 |
Materialen worden alleen getoond wanneer dezelfde literatuurpool deze band en ten minste één extra karakteristieke piek ondersteunt.
Spectrumlogica
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 601 cm⁻¹ is usually not enough for material identification by itself.
Gebruik in de praktijk
Dit type query komt vaak voor bij polymeeridentificatie, screening van onbekende kunststoffen, probleemoplossing bij QC, verificatie van gerecycled materiaal en literatuurondersteunde beoordeling van piektoewijzing.
Veelgemaakte fouten
- Het behandelen van een enkele geïsoleerde band als bewijs van een materiaal zonder ten minste een of twee ondersteunende pieken te controleren.
- Overlap negeren: meerdere functionele groepen kunnen bijdragen rond hetzelfde golfgetal.
- Validatie overslaan wanneer additieven, mengsels, oxidatie of verontreiniging het spectrum kunnen verstoren.
Advies voor verificatie
Wanneer dubbelzinnigheid blijft bestaan, valideer de hypothese met DSC, GC-MS of TGA, vooral voor mengsels, gedegradeerde monsters en gevulde polymeren.
