用Fourier变换红外吸收光谱(FT-IR)和深能级瞬态谱(DLTS)技术研究了γ射线辐照与中子辐照硅,发现γ射线辐照单晶硅中双空位的产生率很低,可以用它帮助鉴别辐照点缺陷。γ射线辐照氢气氛生长硅产生的Si—H中心伸缩振动吸收带数目较中子辐照的为少,只产生了1832,2054和1980cm~(-1)三条新的谱带。本文讨论了它们的模型...
The product was characterized using 1H NMR, 13C NMR, FT-IR and UV/Visible spectroscopies and gel permeation chromatography. The results were compared with those obtained by the heterogeneous coupling reaction of the same monomers.GabrielaInstitute...

The structures of complexes 2–5 were fully determined on the basis of their NMR and IR spectra, and elemental analyses. Moreover, the low-temperature X-ray crystallography of 2, 3, and 5 revealed that the platinum center has a distorted square planar environment, which is probably due to ...

Optical absorption spectra of specimens were measured at about 6 K with use of an FT-IR spectrometer equipped with a continuous-flow type liquid helium cryostat. From the analysis of isochronal annealing behaviors, the binding energies of BeH2 and BeH were determined to be about 2.3 and 3....
