| Abstract: | The far infrared and Raman spectra of the pyridine-I complex in solution in non-polar solvents have been investigated as functions of base concentration and temperature. Attempts have been made to assess the relative contribution of donor-acceptor and classical dipolar interactions to the spectral changes which occur with increasing medium polarity, temperature or donor strength (via the use of picolines as donors). It has been found that the overall evolution of band position, width and intensity is dependent mostly on the medium polarity, reflecting changes in complex stability induced by the surrounding dipoles. However, the irreversible appearance of the I anion seems to be associated with an increase in donor strength. Local dipole ordering, as a function of temperature lowering, clearly also is important for stabilizing the complex. 2 3. [ABSTRACT FROM AUTHOR] |
