Anharmonic Frequency Analysis Results

The results from Gaussian anharmonic frequency calculations can be reported by GaussView via the Results=>Vibrations menu path. The following figure illustrates the form of this dialog when anharmonic frequency results are available:

Anharmonic Frequency Results
The usual frequency table now has three tabs. The selected frequencies in the Harmonic and Anharmonic tabs are coordinated,
and the anharmonic modes involving the selected mode are listed in the
Anharmonic, mode tab (mode 6 in this example).

The following tabs are available in the frequency data table:

The spectra window contains a two controls at the top. The Show Harmonic and Show Anharmonic check boxes toggle the visibility of the corresponding spectra data. The anharmonic spectrum is displayed in red.


Viewing Both Harmonic and Anharmonic Spectra

You can control the appearance of the plot using the Mixture Editor (Plots=>Mixture Editor menu path).
