The Heisenberg uncertainty relation for the three lower 2 electronic states of the H2 + molecule from the internuclear distance R is numerically analyzed using exact electronic wave functions. It is found that states with more energy have more value of the product rp in the region R  6,5 а.е. For the ground state the minimum rp is achieved at R = 0,935 a.e. and differs from the limit value only by 9 %.
