摘要

水阳离子H2O+的可见发射光谱是彗星尾巴的一个显著特征，在实验室放电中经常观察到。然而，到目前为止，可见光电子光谱从未在吸收中被观察到。我们使用可调谐环形染料激光器和速度调制放电来检测吸收，H2O+和D2O+中的a ~ 2 a ~ 1−X ~ 2 B ~ 1可见电子光谱。

First, detection of the visible absorption spectrum of H2O+ and D2O+

The visible emission spectrum of the water cation, H2O+, is a prominent feature in comet tails, and is often observed in laboratory discharges. However, until now the visible electronic spectrum has never been observed in absorption. We have used a tunable ring dye laser and a velocity-modulated discharge to detect the A ˜ 2 A ˜ 1 − X ˜ 2 B ˜ 1 visible electronic spectrum in absorption, in H2O+ and D2O+.
