Abstract
 Fingerprints of antiaromaticity in the negative ion (Li3Al4)(-), this species being realisable via a laser vaporisation technique, are revealed by means of an ab initio quantum-chemical investigation. First, the ground-state equilibrium geometry of this ion is predicted. Also, for the corresponding inhomogeneous electron liquid, the characteristics of the HOMO are studied, both for the square and the rectangular Al-4 geometry in two low-lying isomers of the negative ion. There is no particular sensitivity to the change in geometry of the Al-4 configuration. Therefore, we have calculated theoretically nucleus-independent chemical shifts (NICS), which contain remarkable fingerprints of antiaromaticity. As to future directions, some comments are added in relation to the Shannon entropy.
