Microwave spectrum, structure, low frequency vibrations, dipole moment and quadrupole coupling constants of dinitrogen trioxide

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