Model simulations of laserdriven Cope rearrangements of non-degenerate semibullvalene isotopomers are carried out by fast Fourier transform propagations of representative wavepackets. High selectivities for the isomerization reactions, with reaction probabilities > 80% for specific isotopomers, are
The dynamic syn/anti isomerism resulting from the inversion of the cyano group at the C=N double bond in a series of substituted DCNQIs has been investigated in solution by two-dimensional exchange spectroscopy (2D EXSY). The isomers formed were characterised by 1 H NMR at 223 K to slow down the inv
