An algorithm is employed to elucidate the molecular bond polarizabilities of methylviologen, including their temporal relaxationsfrom Raman intensities. The main characteristic of the Raman excited virtual state of MV is that the excited electrons tend to flow to the molecule periphery and to the bond connecting its two rings due to electronic repulsion. The bond electron densities of its ground state can be mapped out by the temporal bond polarizabilities at the final stage of relaxation.
