Raman & Krishnan: light reveals molecular structure

What changed

Observed a frequency-shifted component of scattered light in liquids and gases, opening a route to study molecular energy changes through light.

Scientific scope

Observed a frequency-shifted component of scattered light in liquids and gases, opening a route to study molecular energy changes through light.
