The above method can be used as a general method of determining molecular weight distribution of polymers.4.Solid-state ~1H wide-line NMR and ~(31)p magic angle spinningNMR were applied to a series of PEI/DNA complex samples with different PEI molecular weights and nitrogen/phosphatemolar ratios,in order to disclose the influence of various structural factors on the interactions and morphology.The results of ~1H NMR spectra showed that the linewidth of the PEI signal was greatly broadened with increasing the N/P ratio.Meanwhile,in the ~(31)p M_AS experiment,the signal was found to shift upfield with the increase of the N/P ratio.Both ~1H and ~(31)P NMR experiments demonstrated that the interaction between two constituents and subsequently the morphology of the complexes vary with the N/P ratio.

Those who have lived and followed the course of events in an intelligent manner during the pontificates of Pius IX, Leo XIII, and Pius X cannot fail to be impressed with the titles given to each by the prophecies of St. Malachy and their wonderful appropriateness: Crux de Cruce Pius IX; Lumen in caelo Leo XIII; Ignis ardens Pius X. There is something more than coincidence in the designations given to these three popes so many hundred years before their time.
