The vibration-rotational structure of the ground A2′ state of the NO3 radical is re-considered, because Hirota (2015) presented an objection to the vibrational assignment of our previous papers (Kawaguchi et al., 2011, 2013; Fujimori et al., 2013). The present study examines the vibrational assignment in the following points, (1) laser induced fluorescence (LIF) spectra observed by Fukushima and Ishiwata in the 1050 cm-1 region, (2) Fourier transform (FT) spectra of vibrational bands from the v4 = 1 state, and a diode laser spectrum of the 2ν4 band. These considerations support our previous assignments, that is, ν3 + ν4 = 1492 cm-1 and ν3 = 1055 cm-1 for 14NO3.
