It is for the first time that we have obtained emission-line spectra of metal atoms during single-bubble sonoluminescence of metal carbonyl W(CO)₆, Mo(CO)₆, Cr(CO)₆ solutions in dodecane and similar spectra during single- and multibubble sonoluminescence of nanodispersed Cr(CO)₆ suspensions in water, 83% H₂SO₄ and 74% H₃PO₄. Nanodispersed suspensions with an average particle size of 15–20 nm were obtained through sonodispersing and filtering Cr(CO)₆ crystals in water. The method for comparing the intensities of two atomic metal lines made it possible to measure the electronic temperatures achieved in cavitation bubbles under different modes of sonolysis that vary in the range of (4.5–16)·10³ K depending on the mode of sonolysis, the type of liquid and saturating gas (He, Ar, Kr) and the acoustic energy entering the solution or suspension. The electronic temperature for multibubble sonoluminescence is, on the average, by (2–2.5)·10³ K less than for single-bubble sonoluminescence for all liquids in question.

这是我们首次获得十二碳烷中的羰基金属W（CO）₆，Mo（CO）₆，Cr（CO）₆溶液的单泡声致发光过程中的金属原子发射线光谱和单峰过程中的相似光谱纳米分散的Cr（CO）₆悬浮液，83％H ₂ SO ₄和74％H ₃ PO _4的-和多泡声致发光。通过声分散和过滤Cr（CO）₆获得了平均粒径为15–20 nm的纳米分散悬浮液。在水中的晶体。通过比较两条原子金属线强度的方法，可以测量在不同的超声分解模式下空化气泡中达到的电子温度，这些温度在（4.5–16）·10 ³  K范围内变化，具体取决于超声分解的模式，液体和饱和气体（He，Ar，Kr）的类型以及进入溶液或悬浮液的声能。对于multibubble声致发光的电子温度是，平均，由（2-2.5）·10 ³  ķ比单气泡声致发光所讨论所有的液体较少。
