The 950-980 Angstrom absorption profiles of the $X\to N2k(b1IIu)(v\prime =3,4,5)$ and $p1\mathrm{<mrow\; data-mjx-texclass="ORD">1</mrow>}\Sigma u+$ bands in $N2$ have been measured at pressure-path length 10-1000 times lower than previous measurements. The oscillator strengths determined, extrapolated to zero pressure, confirm the relative intensities of the electron collision spectra of Meyer, Skerbele, and $Lassettre.1$ Experimental oscillator strengths will be given and the dependence of apparent f-values correlated with the diffuseness of the levels.
