Lower-bound estimates for the ground-state energy of the helium atom are determined using nonlinear programming techniques. Optimized lower bounds are determined for single-particle, radially correlated, and general correlated wave functions. The local nature of the method employed makes it a very s

✦ Synopsis
Reliable ground state rotational energies of propyne have been derived, for the first time, from all available millimeter-wave and submillimeter-wave experimental data together with "forbidden" combination differences providing information on the (\Delta k) spacing of rotational levels. The rotational energies were analyzed by the effective rotational Hamiltonian expressed in the conventional polynomial and in the Padé form. Extrapolation capabilities of both the Hamiltonian forms are discussed. (C) 1995 Academic Press, Inc.
