Hi, I can calculate those basic electronic properties such as energy, charge density, etc. with some softwares. I want to read a book that can tell me how to change these basic properties to some other specific properties such as hyperpolarizability. Can anybody recommend one? Also, does any software can give electron properties of a excited state?
Thanks.
