How can you identify cotton from FTIR?
This page summarizes the recurring FTIR evidence reported for cotton, including the most frequent peaks, supporting functional groups, and literature-backed interpretation patterns. It is a structured evidence page, not a claim of automatic single-spectrum certainty.

Respuesta rápida
cotton is usually reported with a recurring pattern of peaks and functional-group evidence. The most useful approach is to cross-check at least two characteristic peaks before treating it as a match, then verify whether the full spectrum still fits the same material family.
Interpretación de picos
Materiales / grupos posibles
| Grupo funcional | Evidencia |
|---|---|
| Alkyl C-H | 26 |
| Methacrylate | 26 |
| Acetate | 25 |
| C-O single bond | 22 |
| Methoxy (OCH3) | 20 |
| Hydroxyl (O-H) | 17 |
| Ester | 15 |
| Carbohydrate | 13 |
Lógica de espectro
The logic here is evidence aggregation: repeated literature mentions of cotton, repeated peak positions, and repeated functional-group associations. A strong material hypothesis should still be supported by multiple peaks that agree with each other, not by one headline band alone.

Errores comunes
- Llamar a una coincidencia de material demasiado pronto porque está presente un pico famoso.
- Ignorando la preparación de la muestra, cargas, oxidación, agua o aditivos que pueden cambiar el patrón aparente.
- Usando evidencia de la literatura sin verificar si su propio modo de muestreo y calidad del espectro son comparables.
Consejo de verificación
Use DSC, GC-MS o TGA para validar la hipótesis del material cuando el patrón de picos sea ambiguo o mixto.
