The ground-state spectroscopic constants of Be2 revisited

Extensive ab initio calibration calculations combined with extrapolations towards the infinite-basis limit lead to a ground-state dissociation energy of Be2, De=944±25 cm−1, substantially higher than the accepted experimental value, and confirming recent theoretical findings. Our best computed spectroscopic observables (expt. values in parameters) are G(1)−G(0)=223.7 (223.8), G(2) − G(1)=173.8 ...

Computational study on NiAl: ground state, structure, and spectroscopic constants using density- functional theory

The least computational expensive Hamiltonian (methods) and wavefunction (basis sets) for diatomic nickel-aluminum (NiAl), was calculated, along with the ground state, bond length, frequency, and binding energy. Researchers believe nickel-aluminum can be used in high performance turbine jet engines, in place of aluminum-coated nickel. The effects of basis functions under increasing levels of th...

Improved Molecular Constants for the Ground State of HO2

Molecular constants for the ground state of HO2 were recently published TABLE 2 by some of us (1) . These constants were based on measurements of the Revised Molecular Constants for the HO2 Ground State (MHz) frequencies of 17 transitions in the region 2.5 to 5.9 THz combined with Including Combination Differences from à A * r X̃ A 9 previously measured microwave and millimeter-wave measurements...
