The nitrogen trioxide (NO₃) radical is a simple molecule consisting only of nitrogen and oxygen, but because of its high reactivity, there are few examples of its synthesis at densities exceeding 10¹³ cm^-3. In this study, we achieved high density synthesis of NO₃ radicals by using dinitrogen pentoxide (N₂O₅) synthsized at high density and high selectivity using air plasma, and the density was measured by the fabricated optical measuring device. In this paper, we discuss in detail the further densification and selectivity of NO₃ radicals and reaction mechanism through a 0-dimensional reaction model.
