Abstract

In this paper, we present an experimental study of vibrational lattice modes in isotopic mixed crystals of benzophenone- h 10 and - d 10. Our results are discussed using theoretical and experimental data concerning other molecular isotopic mixed crystals. The spectra show two regions; in the first (ν < 100 cm −1) we did not observe an interaction between the various vibrational lattice bands; in the second region (ν > 100 cm −1), the interaction appears clearly. The 111.5 cm −1 and 73 cm −1 torsional modes of benzophenone- h 10 have the same behaviour as the external modes throughout the whole concentration range (0–100% of benzophenone- d 10).
