  • 在實驗所得到的結果裡,我們在波長範圍104 nm-120 nm之間,觀察到了N2(C3Πu←X1Σg+)的吸收光譜,而在110 nm-150 nm之間,也觀察到了N2 (a1Πg←X1Σg+) 的吸收光譜。其中在N2(C3Πu←X1Σg+)有4個振動能階被觀察到;在N2(a1Πg←X1Σg+)則有14個振動能階被觀察到。我們與之前所做的研究相比較時,其位置都非常接近。
    另外,在波長280 nm-360 nm之間,我們觀察到了 N2 (C3Πu→B3Πg)的螢光,也發現了隨著振動能階的增加,其所放出的螢光也相對變弱了。我們與以前所得的資料對照時,其每個振動能階的位置都頗為接近。
