Double Quantum Axes

The '13C DQ' Experiment Type (systematic name 'C[DQ(CC)]') is available for spectra of the INADEQUATE type which contain a normal 13C chemical shift axis in the direct dimension and a double quantum shift axis in the indirect dimension. A modified diagonal at (d,2d) is now drawn, as well as modified cross-hairs at positions (d1+d2) along the indirect double quantum dimension and d1 and d2 in the direct dimension. The crosshairs in other spectral windows will reflect both the d1 and d2 positions, improving the way in which peak positions can be compared between double and single quantum experiments (it may be necessary to amend the panel types for some windows in Windows: Edit Windows for this to work optimally - all single quantum axes should have the same panel type). When the double quantum chemical shift is assigned using the Assignment: Assignment Panel popup, the double quantum shift is automatically deconvoluted into the two constituent chemical shifts. Assignment options are then presented and can be chosen as normal.
