The generation of species in gas phase and long‐lived species in deionized water and d ‐mannitol solution of a bubble discharge in dependence on bubbled gas atmosphere with different O 2 /N 2 proportion are studied. Argon is mixed to enhance the discharge. The optical emission spectra and Fourier‐transform infrared spectroscopy are used to diagnose gaseous species and exhaust gas components, and study the effects of O 2 /N 2 proportion on the species intensities. The aqueous species and OH radical are measured by chemical probes to reveal the role of OH radical on the formation of long‐lived species. The liquid species and exhaust gas are also analyzed varying with O 2 /N 2 proportion to demonstrate the effect of O 2 ‐based radicals on the formation of long‐lived species.
