Handout 8 Linear Combination of Atomic Orbitals (LCAO)
Linear Combination of Atomic Orbitals (LCAO) Now consider a Hydrogen molecule made up of two covalently bonded Hydrogen atoms sitting at a distance of 2d from each other, as shown: Hamiltonian for an electron is: V r dx V r dx m H ˆ ˆ 2 ˆ 2 2 The basic idea behind LCAO approach is to construct a trial variational solution in

A Theory of Justice - Cornell University
courses.cit.cornell.eduCourse schedule: Nearly all assignments from articles will be excerpts. Of course, this is true of all assignments from books, as well. Since readings from Rawls' book, A Theory of Justice, will be directly from this required purchase, I have specified assignments from it in detail, below.
