We focused on valence tautomeric complexes, 35),36) and found that several Co compounds show photo-induced magnetization effects because of the long-lived LMCT. 37),38) Figure 9 shows the magnetic properties of a switchable complex, [[Co.sup.III-LS](3,5-DBSQ)(3,5-DBCat)(tmeda)] (3,5-DBSQ = 3,5-di-tertbutyl-1,2-semiquinonate; 3,5-DBCat = 3,5-di-tertbutyl-1,2-catecholate; tmeda = N,N,N',N'-tetramethylethylenediamine).
When the LMCT band around the visible region was irradiated at 5 K, charge transfer from (dhbq)sup.3]- to Com was induced.
This coincides with the shift of (LMCT) UV-vis band towards higher wavelengths for these three samples (Fig.
Analysis of the electronic structures and orbital components of the complexes indicates that these absorption bands mainly originate from the d(Ru)[pi] + p(QN and Cl ligands) [right arrow] (d(Ru) + [p.sup.*] (NO and QN ligands)) charge transfer processes, which were labeled as MLCT and LMCT processes (L stands for NO, Cl, and QN ligands).
Two bands on the visible region at 383 and 445 nm may belong to S-Ni and O-Ni LMCT transitions [18, 19].
The main changes were in the visible region with a blue shift of LMCT band at 379 nm, respecting those of 1 (383 nm).
Co(II) gives absorption bands also at different wavelengths: due to the [S.sup.-] [right arrow] Co(II) ligand-to-metal charge transfer (LMCT), an intense absorption band in the near UV, between 316 and 340 nm, can be observed.
And the peaks observed near 420 nm may be assigned as LMCT due to the presence of ferrichexacyanate which is assumed by comparison with the solution spectrum of the complex.
"For months, Local 46 has been broadcasting 60-second spots on 1010 WINS Radio to inform commuters of the benefits of union labor providing genuine lath and plaster, as well as cast-in-place reinforced concrete construction," says Bill Hohlfeld, LMCT coordinator.
The high energy bands for this complex are observed at 263 and 346-371 nm, assignable to [pi] [right arrow] [[pi].sup.*] and [pi] [right arrow] [[pi].sup.*] LMCT transitions, respectively.
Similarly, the electronic spectra of Ni(II) complex exhibited absorption band at 22132 [cm.sup.-1] and assigned to be LMCT band and the d-d band suppressed by LMCT band.
