What is the Raman Effect theory?
The Raman Effect is the phenomenon where a fraction of the incident light, when it interacts with molecules in a substance, experiences an inelastic collision. This means that the scattered light has a different frequency, and hence a different colour, than the incident light. This shift in frequency is characteristic of the vibrational energy levels of the molecules themselves. Think of it like striking a bell; it vibrates at its own specific frequencies. Similarly, molecules absorb and emit energy in discrete packets, and the Raman Effect allows us to 'hear' these molecular vibrations by observing the scattered light. It's a powerful tool for understanding the composition and structure of matter.
