Abstract

The infrared spectrum of the ν3 band of N2O3 has been observed at 1304 cm−1 using a slit-jet tunable-diode-laser spectrometer. A total of 439 infrared transitions are fit to a precision of 0.0003 cm−1. Improved ground state rotational constants are calculated from ground state combination differences up to J″ = 20, Ka = 10. A number of weak perturbations are seen in the spectrum characterized by interaction matrix elements of 0.002-0.01 cm−1.

    More recently, ν1 was recorded with a Fourier transform spectrometer under jet-cooled experimental conditions which considerably simplifies the rotational structure [12]. The ν3 band at 1304 cm−1 was also analyzed using a slit-jet tunable-diode-laser spectrometer [13]. A valence-bond study of the origin of the long, weak NN bond was recently published [14].
