    Site-selective probing of iodine 4d orbitals at 13.1 nm was used to characterize the photolysis of CH2I2 and CH2BrI initiated at 202.5 nm. Time-dependent fragment ion momenta were recorded using Coulomb explosion imaging mass spectrometry and used to determine the structural dynamics of the dissociating molecules. Correlations between these fragment momenta, as well as the onset times of electron transfer reactions between them, indicate that each molecule can undergo neutral three-body photolysis. For CH2I2, the structural evolution of the neutral molecule was simultaneously characterized along the C-I and I-C-I coordinates, demonstrating the sensitivity of these measurements to nuclear motion along multiple degrees of freedom

    Beschrieben wurde das Krankheitsbild wohl bereits im 16. Jahrhundert. Dennoch haftet ihm bis heute etwas RĂ€tselhaftes an. Das komplexe regionale Schmerzsyndrom Typ 1 (CRPS 1), frĂŒher auch als Morbus Sudeck bezeichnet, ist ein GefĂŒge verschiedenster Symptome, deren Ursachen bis heute nicht abschliessend geklĂ€rt sind. Entsprechend anspruchsvoll sind Diagnose und Therapi
