The vibrational levels of selected rhombohedral rare earth oxyfluorides, REOF; RE = La, Gd, and Y, were deduced from the room temperature IR absorption and the Raman scattering spectra between 180 and 1000 cm−1 and between 10 and 700 cm−1, respectively. All four IR-active (2A2u +...
Calculation of IR- and Raman-active vibrations of hexacyano complexes of FeII, CoIII, MnII, CrIII, VIIA complete vibrational analysis of the hexacyano complexes of FeII, CoII, MnII, CrIII, VII is presented on the basis of the valence force field method. The calculated frequencies of ...

Infrared active optical vibrations of graphite The infrared refectivity of graphite has been measured for E⊥c and E□c and the frequencies of the "out-of-plane" A 2u symmetry mode and the "in-plane" E ... RJ Nemanich,G Lucovsky,SA Solin - 《Solid State Communications》 被引量: 374...
The influence of strong induced dipolar interactions on the Raman spectrum of the ν3vibration of CX4molecules is discussed in the case of dense, disordered phases. For CF4, in its plastic and its liquid phases, we show that the very peculiar two maximum spectrum can be completely reproduced ...

active nano/microstructures having the strongest localized EM field at hotspots. (2) The Raman scattering photons in SERS are usually directionally emitted, thus the collection optics determine how much Raman scattering generated by the molecules in the hotspot could be transmitted to the detector ...
Raman 光譜儀利用雷射作為來源 (一般為可見或近紅外線雷射),IR 光譜儀一般則採用黑色輻射體 (例如光條) 在中紅外線區內提供能量。 此外,光力學系統也不同,Raman 光譜儀使用全像光柵和十分敏感的 CCD 偵測器,FTIR 光譜儀則是利用干涉計,提供由焦熱電 (DTGS) 或更敏感的光子 (MCT) 偵測器所偵測到的調變輻射...
