Set the default spectrometer frequency (for 1H, in MHz); frequencies for other nuclei will be calculated from it
Switch the default chemical-shift scale between ppm and Hz

Uncheck this box for anisotropic (partially oriented) spectra
Check this box to always include coupling to quadrupolar isotopes.
Isotopomers below this abundance will be ignored in all calculations
Set the maximum scratchfile size (in Kb) for gNMR, gSPG, etc.
Check this box if you always want to go through the File/New dialog when creating a new file
Use symmetry to simplify calculations? Symmetry can be based on numerical values or on variable names.
Check this box to allow use of symmetry in combination with assignment iteration.
Threshold value for the use of perturbation theory to simplify calculations. Set to zero to disable use of perturbation theory.

Check to automatically expand common abbreviations (Et, Ph, …) when importing structures
Check to automatically saturate imported structures with hydrogens
1H nuclei: include all, none, or only those labeled "1H"
C(13) nuclei: include all, none, or only those labeled "1H"
Abundant heteroatom nuclei (S = 1/2 only): include all, none, or only those labeled with an isotope name

Check to let gNMR try to predict shifts for imported structures
Check to let gNMR try to predict coupling constants for imported structures
Change quality of Hardcopies and Clipboard copies
Thickness of lines used for Hardcopies and Clipboard copies, in 1/72"; must be <= 1
Check to use PostScript commands for Laser printer output for improved quality
Check to include PostScript commands in clipboard copies; increases size of copy but improves print quality
Set the magnification factor for the "Copy *8" command
If checked, spectra will adapt their size to their enclosing window
If checked, peaks being assigned will be highlighted in spectra
