Radiative lifetimes of NO A Σ2+(v′=0,1,2) and the electronic transition moment of the A Σ2+−X Π2 system

摘要: Improved measurements of the radiative lifetimes NO A Σ2+(v′=0,1,2) are presented and used to update absolute electronic transition moment for γ bands. The pressure-dependent fluorescence decay rate was measured in a low-pressure, room-temperature, flow cell containing dilute mixtures N2 using time-resolved laser-induced excited with picosecond laser detected microchannel-plate photomultiplier tube. Fluorescence rates were determined an analysis procedure that accounted response detection system measurement noise. Radiative from extrapolation zero pressure. In comparison prior these lifetimes, improved experimental approach result significant improvement precision. accuracy decay-rate confirmed by independent time-cor...
