Abstract
The high resolution infrared spectrum of the polar N$_{2}$O dimer has been observed in the region of N-O stretching fundamental using a tunable diode laser to probe a pulsed supersonic slit jet. An a/b type hybrid band has been assigned and fitted to a planar asymmetric top with slipped parallel structure. The vibrational origin is measured to be 1290.2 cm$^{-1}$ showing a blue shift of 5.3 cm$^{-1}$ from the monomer band origin and 10.5 cm$^{-1}$ from the band origin of the non-polar isomer. The band for the non-polar isomer has also been remeasured and analysed in improved detail. In addition, two trimer bands of N$_{2}$O, located at 1276.56 cm$^{-1}$ and 1285.78 cm$^{-1}$, have been observed and assigned with a/c and a-type transitions, respectively.
