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.

Vibrational and Rotational Spectroscopy of Diatomic Molecules

Spectroscopy is the study of how matter interacts with electromagnetic radiation. Atoms and molecules inter-acting with light will sometimes emit photons at speci c frequencies; these frequencies depend on the energy level separation for whatever transitions caused the photon emission. We can use this to learn about the energy levels
