Karplus equation


The Karplus Equation is given by

Where A, B, C are empirical constants (Hz), and is the azimuthal angle (degrees).

To plot the Karplus equation enter the parameters (i.e., A, B, C) and hit New Plot. Up to 5 plots can be displayed at one time. The Clear button will remove all plots. To see the parameters for each plot hit the Legend on/off button. The Redraw button will refresh the graph. This is useful when the function domain (i.e., ) has been changed. To see the value of each plot at a given point, move your cursor to the desired location then click and hold.
