Raman spectroscopy is a form of vibrational spectroscopy that is used to observe changes in a molecule; these may be rotational, vibrational or some other form. It helps to understand the ...

The pharmaceutical processing industry coats tablets for different kinds of reasons. Tablets can be coated to improve the taste, appearance, swallowability, chemical stability and also to formulate a ...

A SYSTEMATIC investigation at low temperatures of the oscillation and rotation Raman spectra of simple molecules as they are affected by their state of aggregation and by temperature seems to us of ...

(a) Schematic diagram of the pump burst and the Stokes burst in the time domain. N: number of pulses in burst. ∆τ: inter-pulse temporal separation. φ: pulse-to-pulse offset phase. Ω R: Raman frequency ...

Semiconductor nanocrystals are conducting materials with a size that has been reduced to the nanoscale. This size reduction can greatly enhance the physical, chemical, and optical characteristics, ...

Hydrogen is considered a key energy source that is becoming increasingly popular in today’s energy-conscious world. It must be in liquid form for both transport and use. At 298 K, molecular hydrogen ...

The Raman effect is based on light scattering. In most instances, light that “hits” a molecule does not interact with it and so the photon does not lose energy. This process is known as elastic ...
