An important technique in this field relies on firing two laser pulses, the first to initiate a reaction and another to study its progress.
One technique in this paradigm used to track the propagation of quasiparticles SA is known as transient grating spectroscopy. Another technique used in this field is the diffraction image referencing method, also known as the diffraction-difference method. One of the earliest studies in this field examined the dissociation kinetics of cyanogen iodide. An experiment in this field showed that the bond in sodium iodide alternates between ionic and covalent forms. An important technique in this field relies on firing two laser pulses, the first to initiate a reaction and another to study its progress. For 10 points, identify this field of chemistry developed by Ahmed Zewail, which uses ultrashort laser pulses to study chemical reactions over a very short timescale.
