What absorbs at 1410 cm⁻¹ in an FTIR spectrum?
A band near 1410 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.

快速回答
A band near 1410 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.

可能的材料
| 材料 | 支持峰 | 重疊基團 | 引用來源 |
|---|---|---|---|
| Polyethylene | 1410, 1737, 1720 | Alkyl C-H, Methacrylate, Acetate | 1 |
| bone | 1410, 1649, 1660 | Alkyl C-H | 1 |
| ZnO | 1410, 1400, 3430 | Alkyl C-H, Acetate, Methacrylate | 1 |
僅當同一文獻庫支援此波段以及至少一個額外特徵峰時，才會顯示材料。
光譜邏輯
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 1410 cm⁻¹ is usually not enough for material identification by itself.
實際使用
此類查詢常見於聚合物鑑別、未知塑膠篩選、品管故障排除、再生材料驗證，以及基於文獻的峰值歸屬審查。
常見錯誤
- 將一個孤立的譜帶視為材料的證據，而未檢查至少一兩個支持峰。
- 忽略重疊：多個官能團可能在相同波數附近貢獻。
- 當添加劑、混合物、氧化或污染物可能扭曲譜圖時，跳過驗證。
驗證建議
當仍然存在歧義時，使用DSC、GC-MS或TGA驗證假設，特別是對於混合物、降解樣品和填充聚合物。
