普通的FTIR搜尋不支持對此樣品的明確材料鑑定。最近的譜庫名稱為聚(甲基乙烯基醚),但所有報告的譜庫相似度實際上無區分性,且無直接參考或相關文獻證據獨立確認該歸屬。測量的譜帶1084、798和694 cm-1更安全地解釋為指示含有甲基和C-O型醚特徵的有機材料,較低波數的譜帶可能反映取代烴、鹵素相關或其他指紋區貢獻。根據現有證據,更廣泛的方向比特定實體主張更合理。
建議的下一步: Reacquire the FTIR spectrum over the full mid-IR range with improved signal-to-noise and baseline correction, and confirm whether additional C-H stretching, C-O stretching, or halogen-associated fingerprint bands are present. Inspect the 1300-900 cm-1 region in more detail to determine whether the 1084 cm-1 feature is part of a broader ether/alkoxy pattern expected for poly(vinyl ethers) or related oxygenated organics. Check for supporting C-H stretching bands near 3000-2800 cm-1 and for any absence or presence of strong carbonyl absorption near 1800-1650 cm-1 to further constrain the material class. If chlorine is suspected from sample history, use an orthogonal method such as XRF, EDS, or elemental analysis to verify whether halogen is actually present.
