The article discusses the results of studying the emission spectra of liquid hexane C6H14, dichloromethane CH2Cl2, methylene bromide CH3Br upon excitation by pulsed laser radiation. We used a Nd : YAG,laser, λ=1064 nm, tau=5.2 ns, Epulse=0.8 J. The spectral range of 4-20 nm was studied. We used injector with a hole 225 μm ?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.
