Spectroscopy in a Suitcase teacher's resource: UV / Visible Spectroscopy


UV-visible spectroscopy is a technique that readily allows one to determine the concentrations of substances and therefore enables scientists to study the rates of reactions, and determine rate equations for reactions, from which a mechanism can be proposed. As such UV spectroscopy is used extensively in teaching, research and analytical laboratories for the quantitative analysis of all molecules that absorb ultraviolet and visible electromagnetic radiation.

Colour is a well known property of the transition metals. The colour produced as parts of the visible spectrum are due to electron transitions between energy levels. The colour we see is due to absorption by electrons in the d orbitals therefore, if the atom has no d electrons or a full d orbital with 10 electrons, the compound will absorb outside the visible region, and appear white or colourless
