    Abstract:
    Single crystal absorption, emission, and excitation spectra of tris(octamethylpyrophosphoramide)-manganese(II) perchlorate are reported. Crystal field calculations for D3 symmetry support assignments of the observed bands. Interelectron repulsion, normalized spherical harmonic (NSH) trigonal potential, and spin-orbit interaction parameters are fitted, with B=670, C= 3620, DQ=26291, DSIG=-2000, DTAU=2000, and λ=60 cm -1. (The DQ, DSIG, and DTAU values correspond to the conventional crystal field parameter values of Dq=836, Dσ=-239, and Dτ=-93 cm -1.) Intensity borrowing mechanisms are discussed in light of the polarizations and splittings observed. The results are correlated with the previously reported zero field parameters.
