FTIR 證據不支持將此樣品確認為 2-苯基丁-1-醇,因為譜庫匹配置信度低,且無直接或相關文獻證據獨立確認該結構。觀察到的光譜更安全地描述為含氧有機材料,顯示在 3346 cm-1 附近的寬 O-H 帶、2974 和 2893 cm-1 附近的脂肪族 C-H 伸縮,以及 1087 和 1045 cm-1 的強 C-O 區域吸收,這與富含醇的脂肪族組成及可能的醚類 C-O 鍵合一致。1652 cm-1 附近的弱或模糊帶不足以單獨證明更窄的結構歸屬。
建議的下一步: Acquire the full FTIR spectrum with band shapes and relative intensities, especially in the 3200-3600, 1200-900, and 900-650 cm-1 regions, to distinguish alcohol from polyol or ether-containing materials more confidently. Check specifically for aromatic-ring bands near 1600-1450 cm-1 and out-of-plane C-H bands in the 900-700 cm-1 region if 2-phenylbutan-1-ol is being considered. If available, run GC-MS or LC-MS to determine whether the sample is a discrete small molecule rather than a mixed oxygenated material. Repeat FTIR after drying the sample thoroughly, since moisture can broaden the O-H region and complicate interpretation of alcohol-rich materials.
