Abstract
A simple treatment of spin-free quantum theory is applied to three-electron systems, constructing the matrix representations and the corresponding projection operators. The theory is used to treat two example molecules HeH using a model where a helium atom interacts first with a proton and then an electron; and linear H3 where a basis of three 1s functions is used to calculate a set of allowed states. For both systems the energies compare well to earlier, more extensive, calculations.
