Abstract
The constants in the empirical equation were evaluated from published viscosities η and densities d for 23 n‐alkanes. All three adjustable parameters A, B, and T0 were found to vary with chain length. The parameter T0 is predicted with good precision by the Gibbs—DiMarzio theory of the glass transition with a ``flex energy'' ε of 490.8 cal/mole. This value is in agreement with determinations by other methods.
