Hypervirial Functions and Self-Consistent Field Functionslly important to study many-particle systems. Regarding Chemistry these functions offer a great help to study atomic and molecular systems [1, 2], in solid state theory, etc. Recently, their applications have been extended to the field of Molecular Vibrations [3–6].

Importance of the Different Boundary Conditionsts first derivative must tend to infinite more quickly than any finite coordinate power. Notwithstanding, there are a large and important number of problems whose treatment requires finite BC, i.e. conditions imposed on the wave functions for finite coordinate values.

Hypervirial Theorems for Finite 1D Systems. Von Neumann Boundary Conditionsparison there have not been reported in the current literature. However, some of the next theoretical results to be derived in what follows will be suggestible and interesting enough to deserve their examination.

The reader interested In a rigorous mathematical treatment of the evolution operators and their properties is referred to Refs. 4 and 5. A comprehensive summary is given in Apendix I. It immediately follows from the properties of U(t) that . whe
