Luminescences and excited state lifetimes have been measured for four Ir( I) and Rh(I) complexes at 4 K as a function of magnetic field strength. Induced spectra exhibit a B2 dependence while the lifetimes are a function of Be2.

The photolummescence of czsd~chlorobls(l,lO-phenanthroline)inchum(III) chloride and crsdichlorobls(4,4'dimethy~-2,2'-blpyridme)Irilum(IIl) chlonde has been mvestlgated from 2-77 K Based on spectral band shape, errussion decay time, and sWt of orgin wrth change III solvent polanty the luminescmg exated state of each species can be &s&red as metalligand charge transfer.
