由吸收光譜得到吸收截面及震盪強度、計算量子缺陷以指定吸收光譜的特性並與前人的結果做比較。在螢光激發光譜中，測量紫外和可見光螢光並計算螢光截面，在激發波長140-170nm範圍內紫外螢光訊號主要來自B’2Δ→X2Π的躍遷，可見光螢光訊號主要是B’2Δ→B2Π 和 E2Σ+→A2Σ+ 的貢獻。在碰撞消激反應中外加氣體對C(0)及D(0)能態的螢光減弱扮演很重要的角色，同時亦導致C(1), B(9), B(10) B(11)螢光增強，並經由測量半消激壓力可計算NO-M凡得瓦位能井深。

In the absorption spectra, photoabsorption cross sections and oscillator strengths were measured. Quantum defects were calculated to identify the assignments of absorption features. The measured quantities were also compared with previous results. In fluorescence excitation spectra, ultraviolet and visible emissions were observed, and fluorescence cross sections were measured in the excitation region between 140 and 170 nm. The ultraviolet emission is due to the transition B’2Δ→X2Π and the visible emission is associated with B’2Δ→B2Π and E2Σ+→A2Σ+ transitions. In the presence of foreign gas, the collisional quenching effect plays an important role on the fluorescence intensity of C(0) and D(0).We measure the quenching half pressure P1/2 of D(0) respectively. The potential well depth of van der Walls molecule NO-M can be derived from the measured quenching half pressure. In contrast to quenching, the fluorescence intensity of C(1), B(9), B(10) and B(11) are enhanced as the pressure of foreign gas is increased. The enchancement of the fluorescence intensity is attributed to the collisional removal of predissociation.
