该光谱最安全的解释是含氧羰基有机材料,最强支持为酯类或碳酸酯类结构,而非明确归属为碳酸二乙酯本身。关键证据是1722 cm-1处的强羰基带以及1274、1125和1076 cm-1处的多个C-O伸缩特征,加上2923 cm-1附近的脂肪族C-H吸收。虽然谱库最高匹配是碳酸二乙酯,但检索置信度实际上不存在,且没有直接参考文献或紧密对齐的文献证据确认该具体身份。
推荐的后续步骤: Reacquire the FTIR spectrum with full baseline-corrected intensity data and a wider interpretive review of the 1800-650 cm-1 region to better resolve the carbonyl and C-O pattern. Check specifically for ester versus carbonate differentiation by examining the exact shape and relative intensity of the 1274, 1125, and 1076 cm-1 bands. Inspect the 3100-3000 cm-1 and 1600-1500 cm-1 regions for aromatic C-H and ring bands to test whether an aromatic benzoate-type ester is present. If the sample is liquid or extractable, confirm by GC-MS or LC-MS to distinguish Diethyl carbonate from other low-molecular-weight esters or carbonate-containing compounds.
