Nitrogen and Deuterium


Nuclear Quadrupole Coupling Constants

Calculation of the N and D nqcc tensors was made here on ro and reSE structures derived by McGuire et al. [1].  These calculated nqcc's are compared with the experimental values [1] in Tables 1 and 2.  Structure parameters are given in Table 4, rotational constants in Table 5.


 








In Tables 1 and 2, subscripts a,b,c refer to principal axes of the inertia tensor; x,y,z to principal axes of the nqcc tensor.  Ø (degrees) is the angle between its subscripted parameters.  ETA = (Xxx - Xyy)/Xzz.
