Raman and resonance-Raman scattering by erythrocyte ghosts
Biochimica et Biophysica Acta (BBA) - Biomembranes, 19751. We present the laser-Raman spectra of human erythrocyte ghosts, isolated by standard conditions and compare these with the spectra of lecithin liposomes and fat-free serum albumin. 2. The hydrocarbon stretching modes of membrane lipids are temperature sensitive and may serve as a index of hydrocarbon chain motion. 3.

Raman scattering of molecular graphenes
Physical Chemistry Chemical Physics, 2009A simplified theoretical approach for modeling the off-resonance Raman scattering of molecular models of confined graphene (polycyclic aromatic hydrocarbons, PAHs) is presented and compared with the results from density functional theory calculations. This theoretical analysis not only allows for a quick estimate of the Raman scattering activity, but ...

Abstract It is difficult to provide an overview from the physical standpoint of the enormous number of Raman scattering studies performed under pressure. On the other hand, the experimental aspect seems too simple: only a slight modification of the optical scheme is needed to replace a sample by a high-pressure cell, especially by a ...

Raman scattering in Fibonacci superlattices
Physical Review Letters, 1987Raman scattering from acoustic phonons in Si-${\mathrm{Ge}}_{\mathrm{x}}$${\mathrm{Si}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$ Fibonacci superlattices is reported. The main features of the experimental results are determined by the Fourier components of the dependence on position along the growth direction of the photoelastic coefficient.

Raman scattering tensors of tyrosine
Biospectroscopy, 1998Polarized Raman scattering measurements have been made of a single crystal of L-tyrosine by the use of a Raman microscope with the 488.0-nm exciting beam from an argon ion laser. The L-tyrosine crystal belongs to the space group P2(1)2(1)2(1) (orthorhombic), and Raman scattering intensities corresponding to the aa, bb, cc, ab and ac components of the ...

Science, 1972
Laser Raman scattering data for nitrogen, oxygen, and water vapor have been obtained from hydrogen-air and hydrogen-oxygen flames. The resulting ground-state and upper-state vibrational bands exhibit strong asymmetrical broadening. Experimental spectral profiles have been fitted theoretically to give a new measurement technique for the determination of

Raman Scattering in Resonant Cavities
2006The modification of the optical properties of matter due to photon confinement in optical microcavities has been an active field of research in the last ten years. This review addresses the problem of Raman scattering in these optically confining structures. Two completely different regimes exist and will be discussed here.

Rototranslational Raman scattering in hydrogen
Physical Review A, 1989We present a theory appropriate for both the interaction-induced and the pressure-broadened rototranslational Raman spectra based on the binary-collision approximation. Assuming that the anisotropic part of the intermolecular interaction is a small perturbation, we compute the Raman spectrum of hydrogen in the wings of the rotational Raman lines and ...

Surface enhanced Raman scattering
Vacuum, 1982On “rough” surfaces of silver Raman signals of adsorbates are enhanced up to six orders of magnitude. The main aspects of this phenomenon are described and a short introduction to the ongoing controversial discussion is given.

Surface Enhanced Raman Scattering
Physics Today, 2007The remarkable 14-order-of-magnitude signal enhancement that can occur during Raman scattering from molecules on metallic nanostructures turns the normally weak inelastic-scattering effect into a single-molecule spectroscopic probe.
