What absorbs at 422 cm⁻¹ in an FTIR spectrum?
A band near 422 cm⁻¹ can point to several functional groups. Below are the most likely assignments, ranked by how much published evidence supports each — every one traceable to literature (DOI) and cross-validated against our 130,000+ reference spectra and knowledge graph.

빠른 답변
A band near 422 cm⁻¹ is usually interpreted by checking which functional groups repeatedly co-occur there in the literature, then confirming at least one or two additional peaks in the same sample. This page ranks those assignments by accumulated evidence rather than by a single fixed textbook rule.

스펙트럼 로직
This band becomes meaningful only when read with its neighboring peaks. In practice, analysts first look at the assignments above, then check whether the same sample also shows other peaks expected for the same structural motif. A lone band near 422 cm⁻¹ is usually not enough for material identification by itself.
실제 사용
이러한 유형의 질의는 고분자 식별, 미지 플라스틱 스크리닝, QC 문제 해결, 재활용 재료 검증 및 문헌 기반 피크 할당 검토에서 일반적입니다.
일반적인 실수
- 하나의 고립된 밴드를 재료의 증거로 취급하고 최소 하나 또는 두 개의 지원 피크를 확인하지 않는 것.
- 겹침 무시: 여러 작용기가 동일한 파수 근처에서 기여할 수 있습니다.
- 첨가제, 혼합물, 산화 또는 오염이 스펙트럼을 왜곡할 수 있는 경우 검증을 건너뜁니다.
검증 조언
모호성이 남아 있는 경우, 특히 혼합물, 분해된 시료 및 충전 폴리머의 경우 DSC, GC-MS 또는 TGA로 가설을 검증하십시오.
