Cp° = A + B*t + C*t2 + D*t3 + E/t2 H° − H°298.15= A*t + B*t2/2 + C*t3/3 + D*t4/4 − E/t + F − H S° = A*ln(t) + B*t + C*t2/2 + D*t3/3 − E/(2*t2) + G Cp = heat capacity (cal/mol*K) H° = standard enthalpy (kcal/mol) S° = standard entropy (cal/mol*K) t = temperature (K) / 1000.

The interactive plot requires a browser with JavaScript and HTML 5 canvas support.

Select a region with data to zoom. Select a region with no data or click the mouse on the plot to revert to the orginal display.

Moving the mouse pointer over or near a point will display the coordinates of the point. The number of digits shown do not reflect the uncertainty of the value.

On newer browsers the following keyboard commands are supported:

Key	Action
L	Toggle log-log display if possible.
S	Toggle semilog (log Y) display if possible.
K	Move / hide legend (key). Repeated presses of this key will posiiton the legend in the following sequence: upper left, upper right, lower right, lower left, hidden.

Click in or tab to the plot area to enable keyboard commands.

The following components were used in generating the plot:

• jQuery
• jQuery UI
• Flot
• Plugins for Flot:
  • Resize (distributed with Flot)
  • Selection (distributed with Flot)
  • Axis labels

Additonal code used was developed at NIST: plot-data.js.
