We report detailed evidence on the crossing and avoided crossing betwe
en the (X) over tilde(1)A' and 2(1)A' potential energy surfaces of HCN
from ab initio full valence complete active space calculations. The r
ole of three-body effects on explaining the crossing seam and the impl
ications of the latter on reaction dynamics are also briefly discussed
