dc.description.abstractThe emission spectrum of OsN has been recorded in the $3000 - 13000 cm^{-1}$ region using a Fourier transform spectrometer. OsN molecules were excited in a osmium hollow cathode lamp operated with neon gas and a trace of nitrogen. Six bands observed in the $8000 - 12200 cm^{-1}$ region have been classified into three electronic transitions, a $^{4}\Pi_{5/2} -X {^{2}}\Delta_{5/2}, b {^{4}}\Phi_{7/2} - X^{2}\Delta_{5/2}$ and $b {^{4}}\Phi_{5/2}- X^{2}\Delta_{5/2}$ with the 0-0 band origins near 8381.7, 11147.9 and $12127.2 cm^{-1}$, respectively. UA rotational analysis of these bands provides the following equilibrium constants for the ground electronic state: $\omega_{e}=1147.9492(77) cm^{-1}, \omega_{e}x_{e}=5.4603(36) cm^{-1}, B_{v}= 0.493381(55) cm^{-1}, \alpha_{e}= 0.002753(38)cm^{-1}$, and $r_{e}= 1.618023(91){\AA}$. Ab initio calculations have been performed on OsN and the spectroscopic properties of the low-lying electronic states have been calculated. Our assignments are supported by these calculations. The ground state of OsN has been identified as a ${^{2}}\Delta_{1}$, state consistent with the observations for the isoelectronic IrC $molecule^{a,b}$. The $1\sigma^{2}2\sigma^{2}3\sigma^{2} 1\pi^{4}1 \delta^{3}$ electron configuration has been proposed for the ground state and the configurations for the other low-lying electronic states will also be discussed. This work represents the first experimental or theoretical investigation of the electronic spectra of OsN.en_US
