Abstract
Laser induced fluorescence spectrum of FeC between 720-830 nm has been recorded and analysed. 12 electronic transitions have been studied. Transitions from the $\Omega = 3, 2$ and 1 substates of the $X^{3}\Delta_{i}$ state have been observed. The spin-orbit constant of the ground state is determined to be $-211.5 cm^{-1}$, however, the spin-orbit separation between $X^{3}\Delta_{2}$ and $X^{3}\Delta_{3}$ substates is measured to be $-329.809 cm^{-1}$. In addition, hot band transitions from $v = 1$ level of the $X^{3}\Delta_{i}$ state have also been observed. The vibrational separation, $\Delta G_{1/2}$, of the $X^{3}\Delta_{3}$ state was measured to be $852.12 cm^{-1}$.
