Spectroscopic Investigation of the Origin of Distortion of Guest Coronene in Various Sites of n-Heptane Shpol'skii Matrix.
Abstract
N-Heptane was chosen as a matrix because the spectra are sharp (Shpol'skii effect) and because this lattice offers various modes of insertion to the aromatic as evidenced by a multiplet of at least five components, one of them occurring in polycrystals only. The measurement of the zero-field splitting parameters of the different sites which appear in the phosphorescence spectrum has shown that each site corresponds to a different distortion within the triplet state.
