The structure of N2O3 has been determined from the microwave spectrum of seven isotopic species. The detailed structure associated with the following planar configuration is: [graphic omitted] d(N2N3)= 1.864 à ; d(N2O1)= 1.142 à ; d(N3O4)= 1.202 à ; d(N3O5)= 1.217 à ; â O1N2N3= 105.1°â O4N3N2= 112.7°â O5N3N2= 117.5°. The torsional vibrational frequency has been measured as 124 ± 25 cm<sup>â 1</sup>. The quadrupole coupling constants for the nitrosyl nitrogen are Ï aa=â 2.34 MHz, Ï bb= 1.12 MHz, and Ï cc= 1.22 MHz. The dipole moment has been determined as |µa|= 2.05 D; |µb|= 0.54 D; and |µt|= 2.12 D inclined at an angle of 9.1° to the Nâ N bond. On the basis of these data, the bonding is discussed.
