atoms can rotate and vibrate with respect to each other. These vibrations and rotations also have discrete energy levels‚ which can be considered as being packed on top of each electronic level. UV/Vis spectroscopy is routinely used in analytical chemistry for thequantitative determination of different analytes‚ such as transition metal ions‚ highly conjugated organic compounds‚ and biological macromolecules. Spectroscopic analysis is commonly carried out in solutions but solids and gases may also
