Working with 1D spectra

Working with 1D spectra

Working with 1D spectra is much the same as working with ND spectra. You can zoom in on the spectrum with the mouse wheel, zoom either axis selectively by using the mouse wheel on the axis and move the spectrum around with left-drag. The Zoom buttons on the toolbar can be a useful way to exapnd the X and or Y axis to their full limits. Shift + left-drag will zoom in on a region, Shift + Ctrl (Cmd on a Mac) + left-drag will pick peaks and Ctrl/Cmd + left-drag will select/deselect peaks. Note that in order to pick a peak you must drag the mouse over the peak maximum/minimum, not just across its base. Alternatively place a peak with Shift + Ctrl/Cmd + left-click. Use right-click / New Multiplet or shortcut AM to group selected peaks into a multiplet.

Stacking Spectra

You can stack your spectra by going to right-click / Stack Spectra or using the shortcut SK. Increase or decrease the distance between the spectra by changing the Y offset at the bottom of the Spectrum Display. Add a slant by changing the X offset.

Integrating Peaks

You can integrate a peak by selecting it with Ctrl/Cmd + left-click and then going to right-click / Integrate Peak. A small region will be highlighted. Left-drag the edges to increase/decrease the region or left-drag the centre of the region to move it until it spans the full region over which you wish to calculate the integral. The integral value is shown on the display. A new Integral List will also have been created and nested below the corresponding spectrum in the sidebar. If you open this (left-drag into the drop-area or right-click / Open as Module), you will see the integral in the list, showing its bounds and the integral value. The values are updated in realtime as you change the integral bounds. Integrals are shown as coloured regions in the spectrum. To change the colour, double-click on your integral list and select a different Symbol Colour .
