Oral PresentationSession: RA ElectronicThe laser induced fluorescence spectrum of scandium monoiodide (ScI) between 787 and 814 nm has been recorded. ScI molecule was
produced by reacting laser vaporized Sc atoms with methyl iodide (CH3I). Spectra of eleven vibrational bands of the C1Σ
+ - X1Σ
+
transition of ScI were obtained and analyzed. A merged least-squares fit of the measured line positions yielded accurate molecular
constants for the upper levels of the C1Σ
+ state and the v = 1 - 4 levels of the X1Σ
+state. One vibrational band observed at 11627
cm−1
belongs to a sub-band transition of the a3∆ state, which is found to be perturbed by the X1Σ
+ state. Details of the perturbation
and molecular constants obtained will be reported.published_or_final_versio
