Description
Summary:Electronic position and momentum densities are commonly used to study bonding. The Husimi function, a phase-space density, complements our understanding of these usual densities. Its value at position q and momentum k gives the probability for finding an electron in a Gaussian wave packet state centered at q, k. We have examined these functions for H2, LiH, and N2. We find that the Husimi function provides a useful physical decomposition of coordinate density differences into regions labeled by the momentum and of momentum density or density difference into contributions from different spatial regions.
