The hydrogen molecule can be used for determination of physical constants, including the proton charge radius, and for improved tests of the hypothetical long range force between hadrons, which require a sufficiently accurate knowledge of the molecular levels. In this work, we perform the first step toward a significant improvement in theoretical predictions of H{sub 2} and solve the nonrelativistic Schrödinger equation to the unprecedented accuracy of 10{sup −12}. We hope that it will inspire a parallel progress in the spectroscopy of the molecular hydrogen.
