J. Kalcher et Af. Sax, STABILITIES AND STATIONARY-POINTS FOR SINGLET AND TRIPLET-STATES OF THE SI2H- ANION, Chemical physics letters, 215(6), 1993, pp. 601-606
Various stationary points on the (2)A' and (2)ZA'' potential energy su
rfaces (PES) of the Si2H radical and the (1)A', (3)A', (3)A'', and (1)
A'' PES of the Si2H- anion are discussed. The ground state electron af
finity of Si2H is calculated larger than 200 kJ/mol. The vast majority
of the stationary points are strongly non-linear or even symmetricall
y bridged (C-2 nu structures.
