β¦ Synopsis
Molecular ion β¬ragmentation accompanied by intramolecular cyan0 p u p rearrangement has been observed for ylidenemalononitrire dimers containing heteroaromatic or phenyl snlwtituenla.
Among the numerous ylidenemalononitrile dimers lZ2 of general structure 1, those containing thienyl, furyl?

The observation by ESR of intramolecular triplet exciton transfer in some noncoplanar aromatic systems is reported. Activation energies for the process, obtained frome lineshape simulations, are given.
## Abstract Barriers to the Nβ to Nβ transfer of different groups in pyrazole have been calculated at different levels (B3LYP and MP2 with 6β31G\*, 6β311G\*, and CEPβ121 basis sets). Ten groups studied were H, BH~2~, CH~3~, CHO, AlH~2~, SiH~3~, GaH~2~, GeH~3~, SnH~3~, and HgH. Two types of differen
