Light scattering in gases and vapours

Khlcbtsov (1993ab), Khlcbtsov and Mel nikov (1993ab) have started a new research direction, namely, the speclroturbidimetry of fractal clusters. The integral functions defining the spectral properties of nonabsorbing fractal clusters have been studied. 

In summary, the up-to-date development of the turbidity spectrum method provides rather full characterization of the ill-defined disperse systems. 

On the other hand, this element must contain a sufficiently large number of molecules to behave as a subsystem, with all the laws of thermodynamics to be applicable to it. 

Due to Brownian motion, the space element v contains different numbers of molecules at different instants of time. 

we conditionally divide the whole scattering space V into N equal elements of a volume V each.
