The Raman Spectrum of Boron Trifluoride Gas [PDF]

open access: yes, 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

The Raman Spectra of CH3CF3 and CCl2CF2 [PDF]

open access: yes, 1937
Because of the interest attached to ethane and ethane-like molecules in connection with the question of free rotation of the CX3 groups with respect to each other, it was considered that the Raman spectrum of CH3CF3 might yield additional information on ...

Cost-Effective Raman Spectra Acquisition Based on Spreading Code Modulation for Exciting Light

open access: yesIEEE Photonics Journal
Raman spectroscopy is a powerful, non-destructive analytical tool that is widely used across various fields for identifying molecular structures and reactions. However, Raman spectroscopy may be hindered by background and fluorescence noises.

Corrosion Process of Stainless Steel 441 with Heated Steam at 1,000 °C

open access: yesHigh Temperature Materials and Processes, 2017
Stainless steel 441 was oxidized in water vapor containing atmospheres at 1,000 °C to study the contrary effects of water vapor on the oxidization process. The steel in 3.5 vol.

Theory of Raman response in three-dimensional Kitaev spin liquids: application to $\beta-$ and $\gamma-$Li$_2$IrO$_3$ compounds

open access: yes, 2015
We calculate the Raman response for the Kitaev spin model on the $\mathcal{H}$-$0$, $\mathcal{H}$-$1$, and $\mathcal{H}$-$\infty$ harmonic honeycomb lattices.

A micro-magneto-Raman scattering study of graphene on a bulk graphite substrate

open access: yes, 2014
We report on a magneto-Raman scattering study of graphene flakes located on the surface of a bulk graphite substrate. By spatially mapping the Raman scattering response of the surface of bulk graphite with an applied magnetic field, we pinpoint specific ...

Interference spectroscopy with coherent anti-Stokes Raman scattering of noisy broadband pulses

open access: yes, 2011
We propose a new technique for comparing two Raman active samples. The method employs optical interference of the signals generated via coherent anti-Stokes Raman scattering (CARS) of broadband laser pulses with noisy spectra.

The Raman redshift of graphene impacted by gold nanoparticles

open access: yesAIP Advances, 2015
The influence of gold nanoparticles (GNPs) on graphene was studied by Raman spectroscopy. It was found that the contact of GNPs could induce the whole Raman spectrum of graphene to redshift. And the shift of the 2D peak is more obvious than that of the G
