Optical hole burning and matrix effects in a phthalocyanine complex of ruthenium(II)

Abstract

A doubling of the origin is observed in the low-temperature electronic absorption spectrum of the complex carbonyl(pyridine)-phthalocyaninatoruthenium(II) in glassy matrices. The effect is studied by optical hole burning and results suggest a non-degenerate singlet ground state of near C2v symmetry to be invoked. © 1980, All rights reserved.
