我们描述了无多普勒205 nm双光子激发研究原子氢进行使用单模脉冲染料激光系统在低压火焰。激发光谱确认计算的线强度比过渡到3S和3D状态。碰撞增宽率在几个火焰和淬火率相比，在相同的火焰中测量，使用时间分辨荧光测量。
We describe Doppler-free 205-nm two-photon excitation studies of atomic hydrogen performed using a single-mode pulsed dye-laser system in low-pressure flames. Excitation spectra confirm calculated line-strength ratios for transitions to the 3S and 3D states. Collisional broadening rates are obtained in several flames and compared with quenching rates measured in the same flames, using time-resolved fluorescence measurements.
