## Abstract Calculations on phosphole systems using the G3MP2B3 model chemistry show that the phosphorus lone pair is critical to the system's aromaticity. Protonation of the lone pair results in antiaromatic molecules as measured by homomolecular homodesmotic reactions. Attempts to separate out ef

## Abstract The known lone pair orientation effect of an Ξ±βnitrogen atom on ^1^__J__(C,C) couplings was studied using the natural __J__ coupling (NJC) dissection method for the Fermi contact (FC) term. This dissection was performed at the DFTβB3LYP level using three different basis sets. It was ver
## Abstract ^1^H and ^13^C NMR spectra of symmetrically substituted cyclotriphosphazenes exhibit secondβorder effects. The influence of the ^31^P,^31^P coupling constants between ring phosphorus atoms on these effects was studied. Some values of this coupling constant between phosphorus bearing ide
