Inversion of the X-ray restrained wavefunction equations: a first step towards the development of exchange-correlation functionals based on X-ray data. [PDF]

J Appl Crystallogr
The X‐ray restrained wavefunction (XRW) approach could be a useful tool to propose new exchange–correlation (xc) functionals for density functional theory. Here, orbital‐averaged XRW perturbation potentials of atoms (neon, argon and krypton) and simple molecules (dilithium and urea) are extracted and visualized for the first time, and their possible ...

Influence of geometry on the emitting properties of 2,3-naphthalimides [PDF]

, 1992
The luminescence properties of 2,3-naphthalimides have been studied using picosecond and nanosecond spectroscopies. In acetonitrile solution N-phenyl-2,3-naphthalimid(e3 ) is found to emit dual fluorescence with emission maxima at 385 and 490 nm ...
