to represent certain types of molecular structures. Resonance is a key component of valence bond theory and arises when no single conventional model using only single, double or triple bonds can ...

but I think that "resonance structures" are not quantum mechanical superpositions: there are two obvious questions/tests: * do you see the spectroscopy of the double bonds (and my memory is that ...

Three-dimensional triple resonance experiments have become an integral part of ... The magnetization transfer process takes place through multiple, efficient one-bond magnetization transfer steps, ...

Resonance structures of DMA, the hybridization results in the delocalization of electrons (indicated by the dotted line) ...
