Fourier Transform Emission Spectroscopy of the F2Σ+–X2Σ+ System of RuN

“…The v = 0 combination differences for the new transition agree well (within the experimental error) to the corresponding values from the C 2 -X 2 + transition. Although the higher lying electronic states of RuN were not predicted in the previous ab initio calculation (12), the present observation is consistent with the experimental (18)(19)(20) and theoretical (21) results available for the isovalent RhC molecule. Our new transition of RuN is analogous to the E 2 + -X 2 + transition (revised notation, as discussed below) of RhC.…”

“…In the present work we have recorded the emission spectrum of RuN in the 12 000-35 000 cm −1 region using a Fourier transform spectrometer and report the observation of a new 2 + -2 + transition with a 0-0 band near 18 866.4 cm −1 . Although the excited 2 + state was not calculated in our previous ab initio study (12), the present assignments are consistent with, and supported by, the results available for the isovalent RhC molecule (18)(19)(20)(21). In this paper we report the rotational analysis of the 0-1, 0-0, 1-0, and 2-0 bands of the new transition.…”

Electronic transitions of cobalt carbide, CoC, near 750 nm: A good example of case (bβS) hyperfine coupling

“…Furthermore, the hyperfine patterns show that all rotational levels N are present, thereby ruling out structures such as CCoC, which would have half the levels missing because of the zero spins of the equivalent C atoms. Spectra taken using CD 4 are identical to those taken using CH 4 , showing that no hydrogen is present, while the BЉ value of nearly 0.7 cm Ϫ1 is too high for the carrier to be anything other than CoC.…”

Electronic Spectroscopy of Rhodium Mononitride

“…Most of the strong features in the spectrum could be recorded without the aid of a dye amplifier; however, amplification was employed for the DF spectra of some of the weaker bands to enhance the signal quality. Known RhC spectra (6,7) and the internal calibration of the scanning dye laser were used for wavelength calibration. The LIF bandhead positions should be good to Ϯ1 cm Ϫ1 .…”
