## Abstract The variable‐size simplex optimization method is used to reparametrize the __I__ + __A__ and β parameters of an INDO approximation to the perturbed Hartree–Fock calculation of ^13^C chemical shifts in hydrocarbons. The absolute shifts for 39 nuclei in a set of molecules containing up to
An investigation of 13C NMR chemical shifts for I-azaadamantane (l), twelve N-substituted I-azaadamantanes (2-13). 1,3,5-triazaadamantane (14) and nine derivatives (15-23) of 14 is described. The effects of substitution at the nitrogen atom for compounds 1-13 and at C-7 for compounds 14-23 were eval
Isotropic 13C chemical shifts of the ribose sugar in model RNA nucleosides are calculated using SCF and DFT-GIAO ab initio methods for different combinations of ribose sugar pucker, exocyclic torsion angle, and glycosidic torsion angle. Idealized conformations were obtained using structures that wer
## Abstract The ^13^C chemical shifts of the sixteen bridgehead substituted mono‐, di‐, tri‐ and tetrahaloadamantanes (halo = F, Cl, Br, I) and four mixed 1,3‐dihaloadamantanes are reported. The effect of bridgehead halogens on the shift values of carbons in β and δ positions is well correlated by
