THE thermal agitation of the atoms in solids results, as was shown by Raman (NATURE, Jan. 12, 1922, and Jan. 6, 1923), in a noticeable blue opalescence in the interior of such transparent crystals as quartz or ice when they are traversed by a strong beam of sunlight. In his address on the discovery of a new type of secondary radiation (Indian Journal of Physics, Mar. 31, 1928) Raman described observations showing that monochromatic light scattered in this manner by crystals is accompanied by… 
Raman spectra of the second order in crystals
A detailed study has been made of the Raman effect in quartz using the λ2536.5 mercury radiation as exciter. The spectrum consists of 43 Raman lines, nearly half of them have been recorded for the
Low frequency Raman lines in organic crystals
SummaryThe Raman spectra of the low frequency region between 20 and 130 cm.−1 have been recorded for fourteen organic solids and the influence of rise of temperature upto the melting point on these
Raman spectra of the second order in crystals
SummaryThe Raman spectrum of aragonite crystal has been photographed using λ2536·5 excitation. 25 Frequency shifts have been recorded as compared to 17 observed previously. They are distributed as
Edge phonons in black phosphorus
TLDR
Polarized Raman results show the appearance of new modes at the edges of the sample, and their spectra depend on the atomic structure of the edges, and theoretical simulations confirm that the new modes are due to edge phonon states that are forbidden in the bulk, and originated from the lattice termination rearrangements.
Raman radiation studies of nanocarbon materials
Raman spectroscopy is a valuable characterization method applicable to a broad range of materials. Vibrational information enclosed in the Raman spectrum provides access to various material
An Alternate Method for the Determination of the Raman Cross Sections of Optical Phonons in Uniaxial Crystals: Application to LiNbO 3
The present paper is devoted to the derivation of an alternate and simple method based on the rotation of the crystal in view of the determination of the Raman cross-sections of optical phonon in
Optical and vibrational properties of anisotropic layered materials
Atomically thin layered materials with low symmetry which leads to in-plane anisotropy of electronic and optical properties are particularly interesting from the point of view of applications. In
Isotope - Based Material Science
As is well - known isotopes of a given element have identical numbers of protons but differ in the number of neutrons making up their nuclei. Particularly, in crystalline solids, this difference in
