Structure of Small Molecules Via the Coulomb Explosion Method
The so-called “Coulomb explosion” (CE) technique offers a potentially powerful method of studying gross geometric features of a great variety of molecules. During the past few years, new ideas and developments in these techniques have come to fruition. The use of the Coulomb-explosion technique combined with a radically new multi-particle detector, extremely thin film targets, and low-excitation ion source has enabled, for the first time, direct measurements of the complete stereostructure of several small polyatomic molecular ions. These measurements produce 3-dimensional images of the nuclear positions within each individual molecule in a beam. Combining the results of an ensemble of such images yields the nuclear density within the molecule. These developments have presented us with a unique opportunity to directly explore complex nuclear motions within molecules.
