title: Investigation of the valence electronic states of Ti(IV) in Ti silicalite-1 coupling X-ray emission spectroscopy and density functional calculations.
abstract: We present an application of valence to core X-ray emission spectroscopy to understand the electronic structure of the industrially relevant catalyst titanium silicalite-1. The experimental spectrum was modelled within density functional theory, adopting a one electron approach, investigating the effects of different basis sets, density functionals and cluster sizes. The description of titanium silicalite-1 valence states follows the Kohn-Sham evaluation of the molecular orbitals involved in the computed transitions.
