Web26 apr. 2024 · Within resonance Raman spectroscopy, energy of the incident photon has tuned to a specialize resonance in the species of interest. One of the select advantages of resonances Raman spectroscopy versus non-resonant Raman variants remains the enhancement in of Raman signal intensity on-resonance. When a photon is the incident particle, there is an inelastic scattering process called Raman scattering. In this scattering process, the incident photon interacts with matter (gas, liquid, and solid) and the frequency of the photon is shifted towards red or blue. A red shift can be observed when part of the energy of the … Meer weergeven In chemistry, nuclear physics, and particle physics, inelastic scattering is a fundamental scattering process in which the kinetic energy of an incident particle is not conserved (in contrast to elastic scattering).
