P. Li et al., The MACQM calculation of the total energy curve for the equilateral triangle structure of H-3(+) cluster, COMM TH PHY, 32(3), 1999, pp. 467-470
Considering that the cluster H-3(+) can be formed from the interaction of H
+ with two hydrogen atoms, a modified arrangement channel quantum mechanics
method has been used to calculate the total energy curve for the equilater
al triangle structure of H-3(+). The result shows that the curve has a mini
mal energy -1.2306 a.u. at the internuclear distance R = 1.97a(0) = 1.04 An
gstrom. This bond length is in good agreement with the experimental value o
f R = 0.98 +/- 0.02 Angstrom.
