Stretch x-Axis details

This function implements the correction for frequency scale shifts and stretches in IR-spectra. Constant offset corrections (x-axis shifts) and stretches at specified frequencies are possible. The correction is performed by spectral interpolation with a convolution filter.

The Stretch x-Axis command is available in the Mathematics menu.

Stretch x-Axis parameters

The following parameters can be adjusted:

X-Axis shift

Specifies the constant offset correction for the x-axis. The axis will be shifted by the entered value.

Stretch correction

Specifies the stretch correction that will be applied at the selected stretch frequency.

Stretch frequency

Specifies the desired stretch frequency.
