A series of Java tools for learning about the relationship between molecular parameters (size, mass etc) and the form of the spectral trace. These cover rotational, vibrational, ro-vibrational and electronic spectroscopy.
A student should be able to explain how the properties of a molecule relate to the form of its rotational and vibrational spectrum. A student should be able to explain how the lines in a high resolution spectrum are relate to the energy levels of the molecule.
This site is used in lectures to show graphically how the energy levels and spectrum are related. It is also used as a self-learning tool by students and is useful for those whose level of mathematics might restrict their enjoyment and understanding of spectroscopy.
