## Abstract The ^1^H and ^13^C NMR chemical shifts of __cis__‐ and __trans__‐protopinium salts were measured and calculated. The calculations of the chemical shifts consisted of conformational analysis, geometry optimization (RHF/6–31G\*\* method) and shielding constants calculations (B3LYP/6–31G\*

The optimum 14 N pulse lengths in the 13 C-14 N rotationalecho adiabatic-passage double-resonance (REAPDOR) NMR experiment are determined from calculations and from experiments on samples of glycine and L-alanine. The REAPDOR experiment utilizes the adiabatic passages that 14 N spins make between th
