 Title: ABSOLUTE INTENSITIES IN THE VIBRATION-ROTATION SPECTRUM OF OH, AND OSCILLATOR STRENGTHS Creators: D'Incan, J.; Roux, Fancoise; Effantin, C. Issue Date: 1970 Publisher: Ohio State University Abstract: Line radiancy R (erg/$cm^{2}$ sec) in the 1--0 and 2--1 vibration-rotation bands of the OH radical have been obtained using a high resolution infrared `Grille-Spectrometer’, a blackbody and an oxyacetylene flame in thermal equilibrium. From temperature measurements and calculated values of OH partial pressures in different regions of the flame the optical path has been derived. Integrated absorption $S^{v^{\prime}\rightarrow v^{\prime}}_{j^{\prime}\rightarrow j^{\prime}}$ ($cm^{-1}$ $atm^{-1}$) and oscillator strengths have been deduced for the four components (lambda and spin doubling) of the P branch lines $J= 11$ through $J = 17$ in the 1--0 transition, and $J = 9$ through $J = 16$ in the 2--1 transition.
