Molecular scatter

Scattered light that appears even in gases and liquids containing no particles whatever as a result of molecular disorder. In liquids, this disorder causes density fluctuations that effectively scatter light as if they were particles.

Water's molecular scatter is 16 ±2 mFTU at a wavelength of 550 nm. This level, a kind of "natural constant", constitutes a theoretical lower limit for the turbidity achievable by filtration.
