The prospects for using the curves as the input for DR calculations is discussed. 1. Introduction Nitrogen (N 2) is the major constituent of the Earth’s atmosphere and is present in signiﬁcant quantities in cemetery signs to purchaseWebequilibrium internuclear separation. Because local maxima of electron density in molecules coincide with nuclear positions, the concept of molecular structure - such as is incorporated in a bond length - remains valid even without the formal assumption of separation of nuclear and electronic motions, at least for the ground electronic state. cemetery speakers
