Abstract
The radical cation of N,N-dimethylpiperazine is investigated by resona nce Raman spectroscopy and ab initio calculations. The calculations st rongly support the assignment of the vibrational spectrum to a chair c onformation. It is shown that a dramatic geometry relaxation following ionization allows a much more efficient interaction between the nitro gen 'lone pairs' than in the neutral ground state.
