Sonoluminescence (SL) spectroscopy is one of the very few ways to study the plasma formed in solutions submitted to ultrasound. Unfortunately, up to now only very limited emission bands were reported in SL spectra of aqueous solutions, moreover broad and badly resolved. It is shown here that by adding some N and/or CO in Ar, new molecular emissions (CN, N and CO) can be observed and that for some of them rovibronic temperatures can be derived. The paramount importance of Stark broadening in these emissions is underlined, together with the need for data on Stark parameters for molecular emissions.
声致发光（SL）光谱学是研究溶液中超声形成的等离子体的极少数方法之一。不幸的是，到目前为止，在水溶液的 SL 光谱中仅报道了非常有限的发射带，而且很宽且分辨率很差。本文表明，通过在 Ar 中添加一些 N 和/或 CO，可以观察到新的分子发射（CN、N 和 CO），并且对于其中一些可以推导出 rovibronic 温度。这些发射中的斯塔克展宽的至关重要性被强调，同时需要有关分子发射的斯塔克参数的数据。
