What absorbs at 613 cm⁻¹ in an FTIR spectrum?
A band near 613 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.

クイックアンサー
A band near 613 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.

スペクトルロジック
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 613 cm⁻¹ is usually not enough for material identification by itself.
実使用例
この種のクエリは、ポリマー識別、未知のプラスチックスクリーニング、QCトラブルシューティング、リサイクル材料の検証、および文献に基づいたピーク帰属のレビューで一般的です。
よくある間違い
- 少なくとも1～2つの支持ピークを確認せずに、1つの孤立したバンドを材料の証拠として扱うこと。
- 重複を無視: 複数の官能基が同じ波数付近に寄与することがあります。
- 添加剤、ブレンド、酸化、または汚染がスペクトルを歪める可能性がある場合に検証を省略すること。
検証アドバイス
曖昧さが残る場合は、特にブレンド、劣化サンプル、充填ポリマーについて、DSC、GC-MS、またはTGAで仮説を検証してください。
