Electrical discharge generated by nanosecond high voltage (~80 kV amplitude, ~5 ns duration, 1–10 Hz repetition rate) pulses in liquid phase have been studied experimentally. We used optical diagnostics as the main method for discharge investigation. Temporally resolved optical emission spectroscopy showed interesting properties of a ns discharge which is demonstrated by different emission spectra profile compared with the discharges produced by HV pulses of μs duration. However, some known peaks typical for water discharges (Hα, OI) were clearly identified.
