Abstract

The initial results concerning the vibrational mode dependence of the ¹⁹F and ¹H hyperfine interaction in HCF(Ã¹A″) were reported. As such, the ¹⁹F nuclear spin/overall rotation coupling constants display a pronounced energy and mode selectivity which was reasonably explained in terms of variations in both the rotational constant A and nuclear spin/electron orbital coupling constant A. It was anticipated that Zeeman measurements in combination with such results will provide a detailed glimpse into the electronic structure of this prototypical carbene.
