FTIR 证据不支持可靠地分配给特定的谱库化合物。谱库最佳匹配实际上不匹配,且 Top-15 候选物彼此化学不一致。该样品更合理地描述为一种含氧材料,显示高波数 O-H 和/或 N-H 伸缩以及可能包含 S=O 贡献的强指纹区域吸收,但现有证据不足以确认特定的硫化合物、酚类化合物或离散的谱库实体。
推荐的后续步骤: Re-run FTIR on a freshly prepared dry sample and blank the instrument carefully to test whether the 3400-3784 cm-1 features are intrinsic or moisture-related. Inspect the sample in ATR and, if possible, in transmission to see whether the unusual 1795-2066 cm-1 region persists or is an artifact. Compare replicate spectra from different spots to evaluate sample heterogeneity or mixture behavior. If sulfur-containing material is suspected, verify with elemental analysis such as XRF, EDS, or ion chromatography for sulfur-bearing species.
