Declaration: TSpecCollection.ReversedScale [grp: integer]: boolean;
The readonly property ReversedScale returns TRUE if the spectral group defined by the parameter grp exhibits a reversed scale (as, for example, it is common for infrared spectra).

If the grp value is invalid (i.e. grp < 0 or grp > MAXGROUPS) a FALSE value is returned.

Hint: In order to access the spectral collection currently loaded in the Spectral Collection Editor you can use the pre-declared global variable SCData.
