<div>Dear Professor Paolo Giannozzi,</div> <div> </div> <div>Specifically, my system is SrTiO_{3}; It is well-known that there is hybridization between O-2p and Ti-3d. What I want to calculate is the number of shared electrons (or states) between Ti and Oxygen or any quantity that give information on how strong the bond is (that what I called, may be not exactly, "bond overlap population")</div> <div> </div> <div>Please tell me which kind of "bond overlap population" PWSCF can calculate,</div> <div> </div> <div>Thank you very much,</div> <div> </div> <div>Ong Phuong Vu</div> <div>------------------------------------</div> <div> </div> <div>On Apr 23, 2007, at 3:24 , vu ongphuong wrote:<BR><BR>><I> Bond overlap population is defined as a measure of the<BR></I>><I> shared electron density between 2 atoms.<BR></I><BR>this is not a definition: this is what the bond overlap population<BR>is supposed to
