Specific heat data for dioxane lignin (DL) over the range 350-440 K is interpreted using a two-component Einstein specific heat model. There are two major contributions to the vibrational spectrum of DL : one is associated with one degree of freedom and has a low Einstein temperature; the other is associated with two degrees of freedom and has a high Einstein temperature. The higher Einstein temperature reduces when the DL is above its glass transition temperature.
