The structure was determined from the rovibrational spectrum in
the ν3 N2O monomer vibrational band. The geometries of the
monomer subunits were assumed to be unchanged upon complexation.
a
) Angle between the principal axis of the complex and the axis of the
O2 subunit, see figure for the definition.
b
) Angle between the principal axis of the complex and the axis of the NNO subunit, see figure
for the definition.
c
) Vibrational oscillation of the O2 subunit.
