摘 要

本實驗以雙光子共振螢光減量光譜法（optical-optical double resonance fluorescence depletion spectroscopy, OODRFDS）偵測氣態雙原子鈉分子（7d）1Dg電子態的訊號。
實驗結果共得到11個振動能級，181個振轉能階，且振動能級確認至v = 25。利用非線性擬合程式（Dunham程式）求得（7d）1Dg能態分子常數，並建立其位能曲線和法蘭克–康登因子(FCFs)。
另外，在雙原子鈉分子D（3）1Pu和E（4）1Pu電子態上，實驗值和理論值對於C（2）1Pu態來說Te值毫無爭議，但剩下的D（3）1Pu和E（4）1Pu能態便產生了實驗值與理論計算值無法配合的爭議，本實驗之目的便是希望能夠解決此爭議。

ABSTRACT

This work used the Optical-Optical Double Resonance Fluorescence Depletion Spectroscopy (OODR-FDS) technique to detect the（7d）1Dg state of Na2.
In this study, we have observed 181 rovibrational levels, including 11 vibrational levels of the（7d）1Dg state, and confirmed the vibrational levels to v = 25. The Dunham coefficients are determined and them can be derived to construct the potential energy curve and Franck-Condon factors of the（7d）1Dg state.
In the research of D ( 3 ) 1Pu and E ( 4 ) 1Pu state of sodium dimmer, there are no arguments in experimental and calculating about Te value of C ( 2 ) 1Pu state of Na2, but there are not in D ( 3 ) 1Pu and E ( 4 ) 1Pu state.
