Interaction second virial coefficients from a recent H2–CO potential energy surface
Interaction second virial coefficients for mixtures of hydrogen and CO are computed from a recent rigid rotor potential energy surface [J. Chem. Phys. 108, 3554 (1998)]. The calculations include the m...

Response to "Comment on `Quantum Monte Carlo study of the dipole moment of CO' " [J. Chem. Phys. 112, 4419 (2000)]
In our previous publication we have mistakenly claimed that the applicability of the Hellmann–Feynman theorem in fixed-node quantum Monte Carlo calculations is not subject to the manner how the n...

Recently Schautz and Flad concluded that the Hellmann–Feynman theorem holds within the fixed-node diffusion quantum Monte Carlo (DMC) method. We show that the Hellmann–Feynman expression is not in general equal to the derivative of the DMC energy with respect to some parameter lambda if the nodal surface depends on lambda. ©2000 American Institute of Physics.
