Abstract
Spectral holes have been investigated between 7 and 50K on tetra-tert- butyl-tetra-azaporphine (t-Bu-TAP) embedded in a number of polymers. T he maximum position(nu(ph)) of the pseudo wing and the temperature dep endence of the quasihomogeneous hole width(Gamma(qh)) have been measur ed and compared to the known values of the Young's modulus(E') of the matrix. We found that in polymers with larger E' the nu(ph) is higher and the hole width is smaller. The influence of the dynamic mechanical properties as well as the polarity and hydrogen bonding on intermolec ular vibronic coupling is discussed.
