LASER DIODE SPECTRUM OF THE $\nu_{1}$ BAND OF OZONE
Publisher:
Ohio State UniversityAbstract:
Lines of the $\nu_{1}$ band of ozone have been accurately measured in the range $1066-1092 cm^{-1}$. The technique of measurement described elsewhere (1) uses the beatnotes of the laser diode, a stabilized $CO_{2}$ laser and two microwave sources. The generation of harmonies of the microwave frequencies leads to frequency makers distant of 1 GHz from each in a typical 24 GHz range centered on each $CO_{2}$ line (from 9 R(42)) The lines are Doppler resolved and the accuracy of measurement is better than 1 mk. In the recorded spectrum, there are also many lines of the well known $\nu_{3}$ band. A least square fit using the observed frequency of the two strongly coupled $\nu_{3}$ and $nu_{1}$ band leads to new parameters for the $\nu_{1}$ state.
