When a localized perturbation takes place in the Rydberg series, the quantum defect δn of the series shows a value deviated from the normal one of the series. In the homogenous perturbation between Rydberg states (II^-) the electro-vibronic levels show an appearance without any perturbations, even if it exists, because of having the similar rotational constants. The plots of the rotaional levels T(υ, J) against J(J+1) are not crossed, but parallel. The energy shifts are similar in the each levels. In such cases we, therefore, have to detect the existence of localized perturbation from the abnormal quantum defects in the series or deviated rotational constants in the Rydberg bands. Thus studies on the quantum defect is quite important as an evidence of a localized perturbation. In this work we investigate relation between energy spacing, internuclear distance and quantum defect, by using a typical example of the interaction in the 5pπ^1II^-_u (υ=2) and 7pπ^1II^-_u (υ=1) in H_2. Also we discuss an autoionization effect of perturbed rotational levels in the autoionization area.
