I need help with this question: 1. Six-coordinate CR(3) complexes of the type trans-(CrL4A2)n+, generally have magnetic moments consistent with three unpaired electrons, which suggests occupancy of the d orbitals as shown to the right. In principle, a complex with only one unpaired electron could be generated by a suitable choi

2. (7 pts) Locate electronic spectral parameters for the tris(ethylenediamine)nickel(II) ion in solution and the magnetic moment (in Bohr magnetons) for a salt (indicate the counter ion). Spectral parameters should include: wavelengths of absorption maxima (A.), extinction coefficients (E) IODq (lODq is the same as 80) Raca
Sir, I have located the articles and maybe one more. I am having trouble zeroing in on the right answer for the questions and format (like should I put it in a table) since formatting/clarity is graded. Also, how do I go about finding the articles. When I queried on the [Rh(PPh3)3(H)(CO)] or hydroformylation or whatever, I g
