Calculations on the structure, vibrational spectrum, and enthalpy of formation of pentafluoronitrosulfane, SF5NO2

G2 and G3 calculations have been performed to determine the minimum-energy geometry, vibrational frequencies, and enthalpy of formation of SF5NO2, a recently synthesized compound that may act as a greenhouse gas. The strength of the S-N bond has been estimated, as scission of this bond may be the determining factor in the global warming potential of the compound.
