Abstract
The rovibrational spectrum of the Ne-N2O van der Waals complex has been recorded in the symmetric stretching mode region of the N2O monomer (â¼1285 cmâ1) using a tunable diode laser spectrometer in conjunction with an astigmatic multi-pass cell and a pulsed supersonic slit jet. The spectra of both 20Ne-N2O and 22Ne-N2O isotopomers are assigned and analyzed using a Watson S-reduced asymmetric-rotor Hamiltonian. The rotational and centrifugal constants for the excited vibrational state are accurately determined. The band-origin of the spectrum is determined to be ν0 = 1285.12251(18) cmâ1 for 20Ne-N2O and 1285.12363(27) cmâ1 for 22Ne-N2O, which shows a blue-shift of 0.21921 cmâ1 for 20Ne-N2O and 0.22033 cmâ1 for 22Ne-N2O from that of the N2O monomer, respectively.
