Model preparation of H2O hyperspherical modes by visible versus infrared multiphoton excitation
Multiphoton excitation of hyperspherical modes of H2O is simulated using the quasiresonant approximation (QRA) applied to a model of coupled Morse oscillators representing the two O–H stretches....

Hard-sphere mixtures near a hard wall
We report a study of hard-sphere mixtures of different sizes near a hard wall using both the Monte Carlo method and density functional theory. The theory is based on a semiempirical free-energy functi...

It is shown that the recently proposed QCI method including all single and double substitutions has essentially the same computational requirements as the more complete CCSD approach. If properly formulated, the CCSD equations contain at most quadratic terms in the excitation amplitudes. The Journal of Chemical Physics is copyrighted by The American Institute of Physics.
