Abstract

In a recent publication Fong claimed a

C_{s}

site-symmetry origin for certain lines in the

{}^{7}F_{3}

and

{}^{7}F_{4}

regions (corresponding to transitions

{}^{5}D_{0} \to {}^{7}F_{3}

{}^{7}F_{4}

) of the fluorescent spectrum of

{Sm}^{2 +}

in KCl. The present authors point out that the evidence cited for the lines in the

{}^{7}F_{4}

regions (8128.0 and 8122.5 Å) is inconclusive and present experimental proof that both his data as presented and the curves fitted to the data for the lines at 7693.5 and 7694.5 Å are incorrect. Arguments are also presented that the best assignment of site-symmetry origin is

C_{2 v}
