 Title: HIGH RESOLUTION DETERMINATION OF THE INTENSITIES OF $N_{2}O$ Creators: Toth, R. A. Issue Date: 1971 Publisher: Ohio State University Abstract: The line intensities of the $10^{\circ}$1$-00^{\circ}$0, and $02^{\circ}$1$-00^{\circ}$0 and $11^{1}$-01 $^{1}$ 0 bands of $N_{2} O$ have been measured with low sample pressures and high resolution ($0.032 cm^{-1}$). The data are analyzed to obtain the total band intensities, dipole moment matrix elements and the rotational factors. At $300^{\circ} K$ the intensities of the $10^{\circ}$ 1$-00^{\circ}$0, $02^{\circ}$ 1$-00^{\circ}$0 and 11 $^{1}$1-01 $^{1}$0 bands were found to be 36.8, 1.77, and $4.17 cm^{-2}$ $atm^{-1}$ respectively. The lines P (46), P (47), R (43), R (44) and R(45), of the $06^{\circ}$ 0$-00^{\circ}$ 0 band were also observed. The intensities of these lines are enhanced in consequence of the perturbation between the levels, $06^{\circ}$0 and $10^{\circ}$1. Perturbation theory was used to determine the unperturbed positions of these lines and also to obtain the rotational constants and the band center frequency. The band center was found to be at 3466.41 $\pm$ $0.04 cm^{-1}$ and the rotational constants were determined to be, $B_{\Pi 6}^{\circ} = 0.4213$ $cm^{-1}$ and $D_{\Pi 6}^{\circ} = 54 \times 10^{-8}$ $cm^{-1}$. Two lines which belong to the forbidden transition, $06^{2}$0$-00^{\circ}$0 were also observed. These lines, P(29) and R(27), were observed $0.070 cm^{-1}$ to the red from the lines P(29) and R(27) respectively of the $10^{\circ}$ 1$-00^{\circ}$0 band. The center wave number of the $06^{2}$0$-00^{\circ}$0 band was calculated to be 3474.66 $\pm$ $0.30 cm^{-1}$.
