Dynamic Light Scattering Training
the laser wavelength (› For the He-Ne laser ( = 633nm) used in the Zetasizer, this equates to particles less than about 60nm › The scattering produced by such small particles is isotropic i.e. equal in all directions › The intensity of light they produce is proportional to d6 where d is the particle diameter (ie. I α 6d)

The original infrared instruments were of the . dispersive. type. These instruments separated the individual frequencies of energy emitted from the infrared source. This was accomplished by the use of a prism or grating.
Raman spectroscopy
www.chem.uci.eduFrom the Renishaw Raman software the user can select: • a fixed grating measurement with a spectrum 'window' of 400 cm-1 to 1000 cm (configuration dependent) • a unique 'extended scanning' facility allowing the user to choose any Raman shift range up to about 10000 cm-1 (configuration dependent). Essential for extended range
A Second Application of Symmetry
www.chem.uci.eduWe can use character tables to determine the symmetry of all 18 motions and then assign them to translation, rotation, or vibration. We can also tell which vibrations are IR or Raman active. Procedure: 1. Assign x,y,z coordinates to each atom. 2. Determine how each axis transforms for every class of symmetry operation in the group.
