VIS optics
UV/VIS spectroscopy has come of age. Starting with Isaac Newton, it was used to identify the composition of unknown chemical compounds, transition metal ions and gases, organic compounds and biological macromolecules among others. Thanks to the advances of coherent intense visible light sources such as lasers, it became possible not only to identify components of interest present in ppm fractions via spectrophotometry, but also to follow their dynamics via time-resolved measurements. Using ultrafast visible light pulses, femtochemistry studies chemical reactions on extremely short timescales (approximately 10-15 seconds or one femtosecond, hence the name) following the very act of atoms within molecules (reactants) rearranging themselves to form new molecules (products).
