Rayleigh light scattering

WebThe Rayleigh light scattering properties of (H 2 SO 4) a (NH 3) b and (H 2 SO 4) a ((CH 3) 2 NH) b atmospheric molecular clusters have been investigated using a response theory approach. Using density functional theory the molecular structures and stepwise formation free energies of clusters with a and b up to 4 have been re-investigated. The Rayleigh … WebIn this presentation, the sizes of the scattering particles are assumed small compared to the wavelength of incident light. Hence I use Rayleigh's approximation where the particle appears to behave like a dipole and the intensity of light is proportional to the fourth power of the frequency of light.
