High-Resolution Near-Field Raman Microscopy of Single-Walled Carbon Nanotubes [PDF]
, 2003 We present near-field Raman spectroscopy and imaging of single isolated single-walled carbon nanotubes with a spatial resolution of ≈25 nm. The near-field origin of the image contrast is confirmed by the measured dependence of the Raman scattering ...

Journal of Physics C: Solid State Physics, 1975 We present new measurements of the optical mode frequencies in AgGaS2, and suggest reasons why previous determinations are in error. The results indicate that AgGaS2 cannot be regarded as a small perturbation of a zincblende structure, but they are in accord with the predictions of a recent model calculation by Bettini.

Low Temperature Raman Spectra of Dichlorosulfane (SC12), Tetrachlorosulfurane (SC14), Dichlorodisulfane (S2C12) and Dichlorodiselane (Se2Cl2) [1] [PDF]
, 1987 The Raman spectrum of commercial "sulfur dichloride" shows strong lines due to SCl2 and S2Cl2 and weak Cl2 lines at 25 °C, but strong SCl2 and SCl4 signals at -100 °C (the latter are superimposed on the S2Cl2 lines).

Raman spectroscopy of iodine-doped double-walled carbon nanotubes [PDF]
, 2004 We present a Raman spectroscopy study of iodine-intercalated (p-type-doped) double-walled carbon nanotubes. Double-walled carbon nanotubes (DWCNTs) are synthesized by catalytic chemical vapor deposition and characterized by Raman spectroscopy.

Stimulated Raman lineshapes in the large light–matter interaction limit
Optical Materials: X, 2022 Stimulated Raman scattering (SRS) represents a powerful tool for accessing the vibrational properties of molecular compounds or solid state systems. From a spectroscopic perspective, SRS is able to capture Raman spectra free from incoherent background ...

The Raman Spectrum of Boron Trifluoride Gas [PDF]
, 1934 The Raman spectrum of BF3 was photographed using a purified preparation obtained from the thermal decomposition of C6H5N2BF4. Of the lines observed, that with the frequency 888 cm^—1 is certainly, and the band at 439–513 cm^—1 is probably due to BF3. The
