Unexpected expectation values for latent molecular properties.

Latent molecular properties are not exhibited by the given molecular structure but are reproducibly exhibited by the same molecule in a different electronic state or if some molecular interactions have taken place. A consequence of the Holographic Electron Density Theorem, as applied to latent properties, provides a framework that allows an extension of the expectation value formalism, leading to 'unexpected' expectation value expressions for latent properties. Connections of special cases of this approach to earlier density matrix extrapolation methods are pointed out. [ABSTRACT FROM AUTHOR]
