The experimental technique which consists of exciting a mixture of N 2 O and N 2 by radio frequency is very efficient for populating very high vibrational levels. Twelve emission spectra of mixtures of N 2 O and N 2 were recorded with a Fourier transform spectrometer at resolutions of 0.006, 0.004,

✦ Synopsis
Eight emission spectra of CO 2 ϩ N 2 mixtures excited by dc discharge were recorded using a Fourier Transform Spectrometer (Bruker Spectrometer 120HR) with a resolution of 0.003 cm Ϫ1 in the 4.5-m region. Results (wavenumbers, band centers, spectroscopic constants) concerning 13 new vibrational transitions which have not been observed earlier and which occur between highly excited levels (hence their very small population) are reported. The derived spectroscopic parameters allow the reproduction of the experimental wavenumbers with a RMS Ͻ 3 ϫ 10 Ϫ4 cm Ϫ1 .

The nickel complex 2 Ni shows reactivity about 10 3 times greater than that of the cobalt analogue 2 Co . The oxidation ability of the M III (m-O) 2 M III core should be affected by the hindered Tp R ligand system, which can stabilize the 2 oxidation state of the metal centers.
