摘要：

The rotational resolved IR-spectrum of the N2O-N2O van der Waals complex has been observed in the region of 2244-2252 cm(-1) using a computer controlled lead salt diode laser spectrometer. This paper reports on the first observation of a van der Waals mode in (N2O)(2). 1569 absorption lines could be assigned to the combination of the fundamental nu(3)-asymmetric stretch of N2O-monomer with the nu(tor)-van der Waals mode (torsion) of the N2O-dimer. The band origin of the spectrum is observed at nu(0) = 2247.83 cm(-1) which is 20.0 cm(-1) above the nu(3) excitation of the N2O dimer. This deviates considerably from the theoretically predicted value at 37.84 cm(-1) (C. Dutton, ref. 1).
