IR frequencies derived from structure calulation
IR frequencies derived from the computation which produced the structure are shown in the plot below. These data are not adjusted for any expected biases in the computational method.
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 line will display the coordinates of the peak. The number of digits shown do not reflect the uncertainty of the value.
The following components were used in generating the plot:
- jQuery UI
- Plugins for Flot:
Additonal code used was developed at NIST: plot-data.js.
