Computed results for the previous theoretical analysis of infinite and finite dynamic molecular chains containing both parallel and perpendicular components of dipoles (to be referred to as I) are presented. The analysis shows good qualitative agreement with the data observed in polymers above their glass transition temperature, T g , polymer solutions, hydrogen bonding systems in crystalline form or solutions, and also in order‐disorder ferroelectric substances. Double peaks, broadened symmetric or asymmetric peaks with significant shift in frequency below the one free particle loss peak‐frequency are obtained.
