in 1-Aza-adamantane


 


















Calculation of the nitrogen nqcc tensors in 1-aza-adamantane was made here on molecular structures given by B3P86/6-31G(d,p) and B3P86/6-31G(3d,3p) optimization.  Calculated nqcc's are shown in Table 1.  Optimized structure parameters are given in Table 2, rotational constants in Table 3.
