With relaxation symmetry, the geometry of C-36 is optimized at the HF/6 - 3
1G level. Three types of C-13 NMR of C-36 are calculated with B3LYP/6 - 31G
* on the basis of optimized structures. On the other hand, using POAV analy
sis, various carbon atoms and bonds were analyzed and their strains, rehybr
idization and angles between pi - pi orbitals were obtained.
