4. Spectroscopy a) What atomic spectroscopic techniques do you know? (2p) b) What happens in a molecule or atom that is exposed to electromagnetic radiation at the different wavelength ranges, UV-wise and IR. (2p) c) Show with simple sketches how the instruments for absorption and emission work (4p) d) State two advantages of ICP over AAS. Explain the benefits. (2p) 5. Mass spectrometry is a method for determining molecular masses and molecular structures in analytical work. Draw a schematic picture of a mass spectrometer and explain detailed how provincial lip, ionization and separation takes place. (10p) 4.
