description | The infrared spectrum of the van der Waals complex CO-N2O has been recorded in the region of the ν3 N2O monomer vibrational band using a diode laser absorption spectrometer which incorporates a multipass cell and a pulsed jet. The spectrum has been completely analyzed using a normal asymmetric rotor Hamiltonian and the effective molecular constants are accurately determined for both ground and excited vibrational states. The band origin of CO-N2O is observed to shift toward higher wavenumber from the N2O monomer by 2.90540 cm-1. With the aid of an intermolecular potential calculation, we are able to determine that the complex has a T-shaped configuration with the CO forming the leg of the T and the C atom of the CO molecule pointing to N2O. The structural parameters are R″cm = 3.8707(3) Å, θN2O = 80° ± 5°, and θCO = 20° ± 5°. © 1997 Academic Press. |
