The complete dipole oscillator strength distribution for N/sub 2/ has been calculated using the multiple scattering model. From this, the moments of the distribution S(..mu..) and L(..mu..) have been computed for -6< or =..mu..< or =2. The results are analyzed by decomposing the total moments according to the contributions from various subshells and also according to the contributions from various spectral ranges, e.g., discrete vs ionizing excitations. Since many physical properties depend on these moments, this analysis can pinpoint the spectral ranges with the greatest influence. Special attention is devoted to the distinctly molecular effects on the dipole oscillator strength distribution and its moments, particularly for those channels affected by shape resonances. The Rydberg series, for example, are significantly affected. This analysis offers an explanation for the weakness of certain dipole allowed Rydberg series and suggests a tentative new assignment for Worley's third series.
