| Summary: | 碩士 === 國立中央大學 === 物理研究所 === 89 === Production of the fluorescence from the excited states A2Σ+ (υ’ = 0 - 7), B2Π (υ’ = 5 - 8), B’ 2Δ (υ’ = 0 - 2), D 2Σ+ (υ’ = 0 - 4), E 2Σ+ (υ’ = 0) and F2Δ (υ’ = 0) of NO in 160 - 230 nm wavelength region were investigated by using the VUV synchrotron radiation at SRRC as the excitation light source. The fluorescence in the VUV to infrared wavelengths was measured by using a combination of filters and photomultiplier tubes. Quenching rates were measured for gases He, Ar, N2, NO, O2, SF6, CO2 and CF4. Some bands above the dissociation level was observe to emit at the increased buffer gases pressure conditions. These included bands of B(υ’=9), C(υ’=1) among others. Collision related processes were employed to explain these data. Particularly we also find the emission from a(7) and B(0).
