Patent ID: 6869214

Claim:
A computer-readable medium for use with a calorimeter including a digital processor system, a first liquid holder containing a solution containing a plurality of target molecules, and a second liquid holder containing a liquid in which no target molecules are present, said computer-readable medium storing a program for determining a change in volume occupied by the target molecule as the molecule transitions from a first structure to a second structure in response to a change temperature, wherein said program when executed on the processor system causes the calorimeter to: (a) at each of a plurality of temperatures that span a range in which the target molecules transition from the first structure to the second structure, (i) apply a pressure perturbation to the solution in the first liquid holder and to the liquid in the second liquid holder at that temperature; and (ii) record temperature data associated with the pressure perturbation; (iii) from the recorded temperature data, determine the value of a specific property of the substance at that temperature, said specific property being a function of the thermal coefficient of expansion of the target molecules, and (b) from the values of said specific property at the plurality of temperatures, calculate a change in volume occupied by the target molecule.
