Comment on 'Vibrational Spectroscopic Analysis of Silicones:A Fourier Transform-Raman and Inelastic Neutron Scattering Investigation'

摘要

One of the major conclusions of this paper is a purported spectra-structure correlation relating specific Raman bands to chain length in poly(dimethylsiloxane) (PDMS) polymers up to nearly 1000 monomer units in length.The bands of interest,which are claimed to diminish in size as chain length increases,are at 998 and 3052 cm~(-1).A good deal of the discussion and results of this paper are dependent upon this correlation.
