## Abstract On the basis of previous experimental and theoretical studies of lowβmolecular models of living poly(methyl methacrylate) and their coordination interactions, molecular states preceding and involving the propagation step of the anionic polymerization of methyl methacrylate (MMA) were in
## Abstract At the G3(MP2) level of theory the __trans__ isomer 1a of the hypothetical molecule SF~4~(CN)~2~ is more stable than the __cis__ isomer 1b by 8 kJΒ·mol^β1^. The isomerization of 1a to 1b requires an activation enthalpy of 319Β kJΒ·mol^β1^ at 298Β K. The decomposition of __trans__βSF~4~(CN)~
