During light scattering, the majority of scattered light undergoes no change in frequency (or energy), in a process referred to as referred to as elastic or Rayleigh scattering. Raman spectroscopy ...

Fluorescence spectroscopy has great sensitivity, allowing scientists to detect signals from single molecules. But it has limited chemical specificity, making it hard sometimes for researchers to ...

To confirm that the rock picked up by the rover from Mars had potential signs of life, planetary scientists and geologists relied on Indian physicist C V Raman.
