譜庫返回POLYESTER作為最接近的命名匹配,但匹配品質極弱,且更廣泛的證據並不穩固支持特定的聚酯歸屬。觀察到的3477和3623 cm-1譜帶指示羥基官能團,1034 cm-1支持C-O或Si-O型伸縮,1643 cm-1與弱羰基、吸附水彎曲或不飽和官能團一致,而非清晰的鑑別性酯譜帶。由於Top-15譜庫模式內部混合,且無直接或相關文獻證據縮小解釋範圍,最合理的結論是廣泛的含氧材料方向,而非確定的材料鑑別。
建議的下一步: Recollect the FTIR spectrum over the full range with improved signal quality and inspect especially the 1750-1700 cm-1 region for a characteristic ester carbonyl band. Check the 1300-1000 cm-1 region in more detail to determine whether the 1034 cm-1 band behaves more like organic C-O stretching or inorganic Si-O absorption. Dry the sample and rerun FTIR to see whether the 3477/3623 and 1643 cm-1 bands decrease, which would test for adsorbed moisture. If polyester remains a practical possibility, compare against authenticated polyester references and look for the full set of ester-related bands rather than relying on the current weak library hit alone.
