Stark Effect The splitting of spectral lines under the influence of electric field is called Stark effect.
Raman Effect When light of frequency $v_{0}$ is scattered by molecules of a substance which have a vibrational frequency of $v_{1}$, the scattered light when analysed spectroscopically has lines of frequency $v$ where
$v = v_{0} \pm v_{0}$
Zeeman Effect The splitting of spectral lines under the influence of magnetic field is called Zeeman Effect.
Rutherford Effect According to Rutherford on the bombardment of the atoms by high speed $\alpha$ particles, the center of the atom scatters the $\alpha$-particles.
