Helix-coil zipper model

This is a simple demonstration of the Zimm-Bragg zipper model that allows you to see the effect of varying the "s", "sigma" and number of residues.  For more information consult Cantor and Shimmel Vol 3 Chapter 20.  You will need the LabVIEW Runtime Engine 8.2.1 to run these executables.  The links to the files are at the bottom of the page.

2-state Shottky model

Below is also a simple Labview program to examine how a change of the energy gap and number of states affects the average energy and heat capacity.  The program will handle more than 2-states.

Gibbs-Helmholtz Equation
Below is a simple program to graphically display the Gibbs-Helmholtz equation.  Check out what happens when deltaCp is nonzero.
