Abstract: The article discusses the results of studying the emission spectra of liquid hexane C$_6$Н$_{14}$, dichloromethane CH$_2$Cl$_2$, methylene bromide CH$_3$Br upon excitation by pulsed laser radiation. We used a Nd : YAG laser, $\lambda$ = 1064 nm, $\tau$ = 5.2 ns, $E_{\text{pulse}}$ = 0.8 J. The spectral range of 4–20 nm was studied. We used injector with a hole 225 $\mu$m in diameter, operating in a pulsed mode to form a liquid-droplet jet. The emission spectra of these liquid-jet targets were obtained. The obtained spectra were decoded, and the ions emitting in this spectral range were determined.

Keywords: extreme ultraviolet radiation, emission spectra, laser spark, x-ray spectrometer-monochromator, liquid jets.
