The carbonyl stretching vibration of monocarboxylic acid in CCl 4 solution has been investigated. We introduce a new “ m ‐factor” to study the polymerization of this simple RCOOH system. The value of “ m ‐factor” was evaluated and tested in different concentrations and temperatures. Three classes of acid polymers were found as followings: linear dimer in class I ( m ≃2); linear and cyclic dimers in class II ( m ≃4); linear, cyclic dimers, and linear trimer in class III ( m ≃8). A linear relationship between log K 1 and (ϵ−1)/(2ϵ+1) was found.
