“…In previous work, 35 we carried out a spectroscopic analysis of the 6 ⌸ -X 6 ⌬ band system of FeCl and considerably expanded upon previous work. 36 Specifically, we determined rotational constants and vibrational spacings for fine-structure manifolds in both the ground and excited electronic states. The importance of electronically off-diagonal spin-orbit matrix elements involving the 6 ⌸ state was demonstrated through the observation of a very large ⌳ doubling in the 6 ⌸ 1/2 spin-orbit manifold.…”

The three observed bands displayed the rotational structure of a ⍀Јϭ7/2←⍀Љϭ9/2 transition and could be assigned as an excited-state progression in a single vibrational mode. The rotational constant BЉ and its change upon isotopic substitution in acetonitrile ͓CH 3 13 CN͔ was consistent with the assignment of the molecular carrier as the linear FeNC molecule. In analogy with the iron monohalides, which have electronic band systems in the same wavelength range, the transition can be described as a 4p←4s excitation. The derived structure is compared with that of other metal-containing cyanide/isocyanide molecules.

“…This subband exhibited a very large A doubling, indicative of mixing of the excited fine-structure level with neighboring electronic states. With our observations and the previous observation of a 6 0 -A^A band system lying to slightly shorter wavelength, it was possible to derive parameters describing the diagonal and off-diagonal electrostatic + spin-orbit matrix elements 7 of the sextet electronic states associated with the 4p <-4* transition in FeCl.…”
