Raman spectroscopy

From 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

We 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.

132 RARE EARTHS - USGS

World Resources: Rare earths are relatively abundant in the Earth’s crust, but minable concentrations are less common than for most other ores. In North America, measured and indicated resources of rare earths were estimated to include 2.7 million tons in the United States and more than 15 million tons in Canada.
