The nature of the Pariser and Parr ''atomic orbitals" in their non empirical and semiempirical procedures is briefly discussed. It appears that the Pari ser and Parr approximations are generally valid if the overlap matrix can be calculated using Slater atomic orbitals and if the Mulliken approxima

Modes of aggregation of alanine-, norvaline-and valine-containing dipeptides with the have been studied in CC14 solution by using infrared and nuclear magnetic resonance spectroscopies. Solutions of the pure L isomer and of the racemic mixture do not give identical data. At a given concentration, t
