Apakah yang menyerap pada 1370 cm⁻¹ dalam spektrum FTIR?
Jalur berhampiran 1370 cm⁻¹ boleh menunjuk kepada beberapa kumpulan berfungsi. Di bawah adalah tugasan yang paling mungkin, disusun mengikut berapa banyak bukti yang diterbitkan menyokong setiap satu — setiap satu dapat dikesan ke literatur (DOI) dan disahkan silang terhadap 130,000+ spektrum rujukan dan graf pengetahuan kami.

Jawapan pantas
Jalur berhampiran 1370 cm⁻¹ biasanya ditafsirkan dengan memeriksa kumpulan berfungsi yang sering wujud bersama di sana dalam literatur, kemudian mengesahkan sekurang-kurangnya satu atau dua puncak tambahan dalam sampel yang sama. Halaman ini menyusun tugasan tersebut berdasarkan bukti terkumpul dan bukannya peraturan buku teks tetap tunggal.

Bahan yang mungkin
| Bahan | Puncak sokongan | Kumpulan bertindih | Sumber dipetik |
|---|---|---|---|
| Chitosan | 1370, 1650, 1655 | Alkyl C-H, Amide, Acetate | 1 |
| Cellulose | 1370, 1735, 1650 | Alkyl C-H, Acetate, Methacrylate | 1 |
| SiO2 | 1370, 1739, 699 | Alkyl C-H | 1 |
| polyaniline | 1370, 1565, 1570 | Amide, Alkyl C-H, Methacrylate | 1 |
| Polyvinyl Alcohol | 1370, 1141, 1640 | Alkyl C-H, Methacrylate, Acetate | 1 |
Bahan hanya dipaparkan apabila kumpulan literatur yang sama menyokong jalur ini dan sekurang-kurangnya satu puncak ciri tambahan.
Logik spektrum
Jalur ini menjadi bermakna hanya apabila dibaca dengan puncak-puncak jirannya. Dalam amalan, penganalisis terlebih dahulu melihat tugasan di atas, kemudian menyemak sama ada sampel yang sama juga menunjukkan puncak lain yang dijangka untuk motif struktur yang sama. Jalur tunggal berhampiran 1370 cm⁻¹ biasanya tidak mencukupi untuk pengenalpastian bahan dengan sendirinya.
Penggunaan dunia sebenar
Jenis pertanyaan ini biasa dalam pengenalpastian polimer, saringan plastik tidak diketahui, penyelesaian masalah QC, pengesahan bahan kitar semula, dan semakan tugasan puncak yang disokong oleh literatur.
Kesilapan biasa
- Menganggap satu jalur terpencil sebagai bukti bahan tanpa memeriksa sekurang-kurangnya satu atau dua puncak sokongan.
- Mengabaikan pertindihan: pelbagai kumpulan berfungsi boleh menyumbang berhampiran nombor gelombang yang sama.
- Melangkau pengesahan apabila bahan tambahan, campuran, pengoksidaan, atau pencemaran boleh memesongkan spektrum.
Nasihat pengesahan
Apabila kekaburan masih ada, sahkan hipotesis dengan DSC, GC-MS, atau TGA, terutamanya untuk campuran, sampel terdegradasi, dan polimer terisi.
