✦ Synopsis

The apparent spin-orbit splitting of 4d energy IeveIs in cadmium metal and cadmium dimethyl is discussed in terms of crystal-fieId and band-broadening models. The use of nuclear field gradients from Mossbauer and NQR measurements in distinguisbing between these t\vo models is evaluated by CNDO calculations on cadmium dimethyl and a cadmium atom cluster (Cd&

The calculations suggest that the use of nuclev field gradients cannot reliably distinguish between crystal-field and band-broadening mechanisms.
