Nuclear Quadrupole Coupling Constants


in Methylgermylbromide


 







 
 
In Table 1, the subscripts a,b,c refer to the principal axes of the inertia tensor.   Subscripts x,y,z refer to the principal axes of the nqcc tensor.  The nqcc y-axis is chosen coincident with the c-axis.  Ø (degrees) is the angle between its subscripted parameters.  ETA = (Xxx - Xyy)/Xzz.
 
RMS is the root measn square difference between calculated and experimental diagonal nqcc.  RSD is the residual standard deviation of the calibration of the computional model for calculation of the nqcc's.
