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

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.

This is a way of resolving the scattering variable Q = (4π/λ) sin(θ/2) where λ is the neutron wavelength and θ is the scattering angle. This is performed by either step-scanning or using a position-sensitive detector. The main types of elastic scattering instruments are diffractometers (either for single-crystal, powder diffraction or

VIBRATIONAL SPECTROSCOPY

• Rayleigh scattering, is elastic because the excitation begins and ends in the same vibrational state. Elastic scattering of photons is far more likely than inelastic scattering of photons. • Stokes and anti-Stokes scattering, is inelastic because the initial and final energy levels of the excited electron are different vibrational states.
