## Abstract __Ab initio__ calculations at the MP2/6β311++G\*\* level of theory led recently to the identification of 13 stable conformers of gaseous glycine with relative energies within 11 kcal/mol. The stability of every structure depends on subtle intramolecular effects arising from conformation

The x-ray molecular structures of five chiral phosphoramidates derived from N-phosphorylated nitrogen mustard were determined and the molecular parameters are discussed. The value of the torsion angle of the O=P-N-H function which determines the packing of the molecules was found to determine also t
## Abstract The conformation of 1βphenylβ1β(1,2βdimethylβ5βpyrrolyl)β2β(2βmethylβ5βbenzoylβ1βpyrroly)ethanol, with characteristics of a molecular propeller, is stabilized by intramolecular hydrogen bonding as detected by ^1^H NMR, NOE difference experiments, 2D NMR, COSY, ^13^C NMR, HETCOR, HMBC an
