The structure, binding energy, and Vibrational frequencies have been d
etermined for ScCO2+. The inserted OSc+CO structure in the (1)A' state
is the most stable isomer and Lies 43.2 kcal/mol below the ground-sta
te Sc+ + CO2 asymptote. The linear eta(1)-OSc+-OCO (3) Delta state is
bound by a charge-quadrupole interaction and has a binding energy of 1
3.9 kcal/mol. (C) 1997 John Wiley & Sons, Inc.
