Carboxylic acid dianions (fumarate, maleate and succinate) play a role in coordination chemistry and to some extent also in the biochemistry of body cells. A team has now analyzed their electronic ...

“Most techniques for studying molecular structure, such as X-ray diffraction and electron scattering measure the total electron distribution,” Villeneuve told PhysicsWeb. “We were able to isolate a ...

The properties of equivalent orbitals, as defined in previous parts, are examined in more detail. It is shown that the character of an equivalent set can be deduced knowing the symmetry group of a ...

Molecular geometry of the trans- and cis-isomers fumarate and maleate (above, left to right) together with their hydrogenated molecule, succinate−dianions (below) . Carboxylic acid dianions (fumarate, ...
