| Popis: | The weak overtone transitions of nitrous oxide, N 2 O, have been investigated around 1.05 μm by Fourier Transform spectroscopy and intracavity laser absorption spectroscopy (ICLAS) using different vertical external cavity surface emitting lasers (VECSELs). Nine bands were rotationally analyzed revealing the occurrence of some local rotational perturbations. The interaction mechanisms and the perturbers are univocally assigned on the basis of the effective Hamiltonian model. In two cases, interpolyad couplings were evidenced indicating that the polyad version of the effective Hamiltonian has to be extended to include Coriolis and interpolyad anharmonic interactions. |
