Infrared and Raman spectra of MoO3 molybdenum trioxides and MoO3xH2O molybdenum trioxide hydrates [J]. Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 1995, 51(8): 1323-1344....
但是实际上得到的Raman的峰是一个在Raman峰本身的形状,(natural line shape),仪器的传输函数(instrumental transfer function)和无序诱发的振荡的分布(disorder-induced distribution of vibrators)之间的卷积积分(convolution).它经常被认为是高斯或者Voigt函数(一个完美的lorentzian和高斯函数的对称卷积)。 2.通常,晶体的...
UV Raman spectra of these samples indicate thatthe mixed phases ofanatase and rutilecoexistin the surface region.Namely, when the TiO2 sample is calcined at 700– 750 oC,the phase junctions betweenanatase and rutileare derived on the surface ofthe rutile TiO2,as characterized byUV Raman spectrosc...
Hence, Stokes lines have stronger intensity and are generally measured in Raman spectroscopy3. Owing to the physical mechanism at their basis, Raman spectra are sensitive to any change in the material that alters the energy of optical phonons, like the breaking or formation of chemical bonds, ...
Raman spectraquantitative Raman analysissurface statesMoO3ZrO2 prepared by different methods are distinctive in catalytic behavior. MoO3ZrO2 (MZ) obtained by impregnating crystallized ZrO2 and then calcining at high temperature is a catalyst for partial oxidation. However, MoO3ZrO2 (MZH) obtained by ...
The Raman spectra of P[sub 4] and P[sub 2] molecules have been studied in nitrogen, argon, krypton, and xenon matrices at 15 K. The vibrational frequencies of the P[sub 4] molecule are up to 14 cm[sup -1] higher than the experimental gas phase data. This apparent blue-shift is ...
举例:In order to obtain better confirmation on the presence of H4SiMo12O40, Raman spectroscopic investigation was also conducted, because Raman spectroscopy is a sensitive technique to study supported metal oxide and it is complementary to IR investigation. The Raman spectra of the MoVI@mSiO2 and...
The Raman spectra are discussed on the basis of a factor group analysis and in terms of the influence defects': Mo nonstoichiometry and a disordered structure involving the disposition of Na+ and Bi3+ ions. The characteristic of the NaBi(MoO4)2 Raman spectra is its high Raman scattering ...
The Raman spectra of glassy and liquid As xS yBr z samples from the glass-forming region of the As-S-Br system were studied and analyzed in terms of basic structural units. The structural network based on AsS 3 pyramidal units connected via S-bridging atoms is supplied with S 2As-AsS 2...
Structure and polarized infrared and Raman spectra of the solid complex of betaine and maleic acid (1:1) Crystals of betaine maleic acid (BHM) of the formula [(CH 3 ) 3 N + CH 2 COOH]·[HCOO CH CH COO ] are monoclinic, space group P1n, with a = 6.138(3), ... M.M Ilczysz...
