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.

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 ...

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 ...

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
