LASER SPECTROSCOPY OF THE $C {^{1}}\Sigma-X {^{1}}\Sigma$ TRANSITION OF YI
TL;DRAbstract
Electronic transition of YI has been studied using laser ablation/reaction supersonic free jet expansion and laser induced fluorescence spectroscopy. YI molecule was generated by laser ablation of an yttrium rod in the presence of $CH_{3}I$ vapor. High resolution laser induced fluorescence spectrum of YI has been recorded in the near infrared region $11850-13000 cm^{-1}$, using a cw single frequency Ti:sapphire ring laser. 15 bands of the $C {^{1}}\\Sigma-X {^{1}}\\Sigma$ transition of YI have been rotationally analyzed. Each band displays the pattern of R and P branches only, which is characteristic of a ${^{1}}\\Sigma - {^{1}}\\Sigma$ transition. Least squares fit of all the available lines of YI molecule yielded molecular constants for both the $X {^{1}}\\Sigma$ and $C^{1} \\Sigma$ states.
