a
“C” prefixes data for empty capsule.
“F” prefixes data for capsule and sample.
b
Molecular Weight = 101.9613.
c
Original heat and mass data are available but it was not possible to trace the corrections applied to yield the molar values (col. 5), which were used in evaluation of the smoothing function (eq. (3) of [2]).
