1. 这个峰一般来说是 C=O 双键的峰,可是你说是无机物,很有可能是某一 个基团的倍频峰,看看 820 左右或者是某两个峰的叠加。 2. 也有可能是你在测量过程当中由于激光引起的碳化物质。还有一种可能 就是 C=C. 3. 拉曼在 1610-1680 波数区间有 C=N 双键的强吸收 十一、 1 红外分析气体需要多高的分辨率?

太原市考古研究院利用显微拉曼揭示了山西太原新石器时代仰韶(公元前3000-2700年)陶器黑、红的装饰,发掘了红色装饰的颜色来源于赤铁矿和磁铁矿,对表面的黑色装饰进行了研究,揭示出黑彩矿物类型,根据Mn/Fe比和结晶类型可分为两种类型:一类为,低MnO2/Fe2O3比的矿石,为锰铁尖晶石和磁铁矿:另一类,为高MnO2/Fe2O3比...
The Raman spectra of bixbyite, Mn 2 O 3 , were measured up to 40 GPa at room temperature. Mn 2 O 3 undergoes a phase transition from the C-type rare earth structure to the CaIrO 3 -type (post-perovskite) structure at 16–25 GPa. The transition pressure measured in Raman spectroscopy...

Raman spectroscopy has proven to be a powerful, local structural probe for MnO2.δ-phase MnO2 has strong Raman-active (Mn-O) stretching transitions at 646 and 575 cm-1. A somewhat weaker transition at 510 cm-1 is also prominent but less intense in most δ-phase MnO2 samples. All three ...
Thus, the 3mn − 3 optical modes are divided between intermolecular translational (3m− 3), free and/or restricted molecular rotations (mNfr, where Nfr is the number of rotational degrees of freedom of the molecule), and the intramolecular vibrations or fundamentals (Nf = 3mn − 3m ...

It is demonstrated that ligand distortion in the MnII-NO system is a valid mechanism for causing the resonance enhancement of the Mn-N-O bending mode, similar to that observed in the FeII-CO system (Yu, N.-T., E. A. Kerr, B. Ward, and C. K. Chang. 1983. Biochemistry. 22:...
