Abstract
Upper and lower bounds are calculated for the nonrelativistic electronic ground state energy of the1Σ +g state of molecular hydrogen using the method of variance minimization with Hylleraas-CI functions. In order to solve the occurring new integrals centered interparticle coordinates were introduced.
