Determination of the thermal energy and its distribution in peptides


The mean thermal energy and its distribution has been calculated for various peptides. The table, figures, and analytical expressions provided in the paper can be used to determine the mean thermal energy and its distribution in peptides in a very simple way, without having to use complex mathematics. Accuracy is ∼±6%. The same expressions can be used for most organic compounds with an estimated accuracy of ∼±10%. Data for W(CO)6, the “thermometer molecule,” are also given.
