Tap-water samples were collected from participants' homes and were tested at the Trace Element Analysis Core at Dartmouth College using inductively coupled plasma mass spectrometry (ICP-MS) with a quadrupole collision cell 7500c Octopole Reaction System ICP mass spectrometer (Agilent) and helium as a collision gas to remove polyatomic interferences, as described previously (Karagas et al.

If one simply writes, for a particular assembly of N nuclei and n electrons in a polyatomic molecule, a full hamiltonian operator that includes only terms for the kinetic energy of both electrons and nuclei with the electrostatic potential energy of all their interactions--which corresponds to the standard hamiltonian in the practice of quantum chemistry apart from an inclusion here of nuclear kinetic energy, one finds clearly that the result of the solution of the Schroedinger equation, necessarily by purely numerical means, yields only an energy, or rather prospectively a manifold of energies of all states discrete and continuous.
