The electronic spectra <strong>of</strong> Ni(H) species are <strong>of</strong> especial interest existing in all<br />

coordination numbers from seven through two [31]. Also, there may be exist more<br />

electronic data for Ni(H) than for any other metal ion [31]. The electronic spectral data<br />

<strong>of</strong> Ni(H) complexes in 10-5 M DMF solutions are listed in Table 3.2 and the spectra<br />

are given in Figs. 3.14 and 3.15. The intraligand n —> fr * transitions <strong>of</strong> free ligands<br />

have suffered considerable shift in complexes. The ground state <strong>of</strong> Ni(H) in an<br />

octahedral coordination is 3A2g and expects three spin allowed transitions 3T2g(F)
