Within the lagrangian formalism in classical field theory Noether's theorem is generalized so as to abolish the role of invariance considerations in it. Examples of application of the generalized formulation are presented for comparison with the usual formulation. It is shown that symmetry transform
## Abstract Energyβshifted perturbation theory is studied in connection with corrections to Koopmans' theorem. The first three vertical Ionization potentials of N~2~, C~2~H~2~, and HCN are computed with basis sets of doubleβzeta Gaussianβtype orbitals and doubleβzeta GTO plus polarization functions
The effect of resonant intramolecular interactions upon vibrational energy transfer is studied using classical and quantum perturbation theory. It is shown that cancellations attributed previously to quantum interference may equally well be ascribed to a classical mechanism.
