One of the first observed manifestations of such energy retention was the appearance of the Lewis-Rayleigh afterglow which is well-established as arising from the recombination of nitrogen atoms produced in an electric discharge. The long-lived low-lying triplet states of $N_{2}, A^{3}\Sigma_{u}^{+}$ and the $W^{3}\Delta_{u}$, have received considerable attention as energy depositories and the $B^{\prime}$ $^{3}\Sigma_{u}^{-}$, although less subject to observation, undoubtedly plays a similar role in many environments. In the singlet manifold, the lower excited states of molecular nitrogen, $a^{^{\prime}1}\Sigma_{u}^{-}, a^{1}\Pi_{g},$ and $w^{1}\Delta_{u}$, are of interest as being relatively long lived, with the $a^{\prime}$ under consideration as a possible precursor in the formation of auroral NO. Quantitatively, the relatives significance of the roles of the above-mentioned states in participating in energy-transfer processes depends on the values of their radiative lifetimes and the associated oscillator strengths. We have made a series of measurements on the oscillator strength for transitions connecting such low-lying singlets and triplets with the ground state and we present our results to this point. For the $\nu = 0$ level of $a^{^{\prime}1}\Sigma_{u}^{-}$, the lowest excited singlet level of nitrogen, a life-time of 0.013 sec is obtained. en_US dc.format.extent 161808 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title ABSORPTION OSCILLATOR STRENGTHS FOR MOLECULAR NITROGEN en_US dc.type article en_US
