Abstract Low spin di(bromo)phthalocyaninatometalates of tervalent iron, ruthenium and osmium ([MBr2Pc2-]-) are formed by the reaction of [FeBrPc2-] or H[MBr2Pc2-] (M = Ru, Os) with excess bromide in DMF or THF and isolated as (nBu4N)+ salts. The electronic spectra show the typical π- π*- transitions (B, Q, N region) of the Pc2- ligand together with a number of extra bands due to trip-multiplett and (Pc, Br → M)CT transitions. νs(MBr) is observed in the resonance Raman (RR) spectrum (RR enhanced for M = Fe, Ru) at 161 cm-1 (Fe), 183 cm-1 (Ru) and 192 cm-1 (Os), νas(MBr) at 251 cm-1 (Fe), 234 cm-1 (Ru) and 218 cm-1 (Os) in the FIR spectra. The RR spectra obtained by excitation at low absorbance between the B and Q region are dominated by the intraconfigurational " Γ7 →Γ 8" transition due to spin orbit splitting of the 2T2g ground state for Fe at 583 cm-1, Ru at 1026/1050 cm-1 and Os at 3131 cm-1 . In the MIR resp. NIR spectra vibronically induced transitions are observed for the Ru or Os complex.

Using techniques of delayed pulsed-field ionization zero-kinetic-energy (ZEKE) photoelectron spectroscopy, we have resolved spin-orbit structure in the rotational profile of the origin band in the non-resonant two-photon threshold photoionization of propyne. Both the rotational and spin-orbit characteristics of this band are well-simulated by a simple model that assumes the spin-orbit splitting of acetylene cation in combination with the rotational constants of the neutral propyne ground state. This result, combined with very little evidence for photoionizing transitions terminating on vibronically excited states, suggests that the structure of the propyne cation structure is very close to that of the neutral ground state and very little altered by Jahn-Teller distortion.

Spin Orbit Splitting

Abstract The Hel and Hell photoelectron spectra of the title compounds have been recorded and an­ alysed on the basis of comparison with chlorotrifluoromethane and methyl halides. Spin-orbit splitting could be observed in the ground state of CF3I+ where it amounts to 0.73 eV and is unresolved in CF3Br+. Vibrational fine structure observed in two band systems D and E in CF3Br+, and X and E in CF3I+ is also discussed.

Abstract The optical obsorption spectrum of Co(II) ions doped in magnesium thallium sulphate hexahy­ drate is studied at room and liquid nitrogen temperatures. The crystal exhibits characteristic absorption of the Co(II) ion in the visible and near infrared. The observed bands are assigned to transitions from the ground state 4T1g (F) to various excited quartet and doublet levels of the Co(II) ion in octahedral symmetry. The splitting of one of the bands at liquid nitrogen temperature is explained to be due to spin-orbit splitting. All band positions have been fitted by the parameters B, C, Dq and ξ.
