9.6-Micron Band of Telluric Ozone and Its Rotational Analysis

The 9.6‐micron band of atmospheric ozone has been investigated by means of high resolution measurements of the solar spectrum from the Jungfraujoch in Switzerland. A rotational analysis confirms its assignment as the v₃ fundamental and results in the following values for the vibrational frequency and rotational constants: $${\nu }_3{\text{=1042.1}}_6\hspace{0.17em}{\mathrm{cm}}^{\text{−1}}{\text{;\hspace{0.17em}\hspace{0.17em}A=3.50}}_2\hspace{0.17em}{\mathrm{cm}}^{\text{−1}}{\text{,\hspace{0.17em}\hspace{0.17em}B=0.440}}_1\hspace{0.17em}{\mathrm{cm}}^{\text{−1}}{\text{,\hspace{0.17em}\hspace{0.17em}C=0.388}}_3\hspace{0.17em}{\mathrm{cm}}^{\text{−1}}.$$ The decrease of all three rotational constants relative to the ground‐state values suggests an appreciable Coriolis interaction with the v₁ fundamental.
