Hello!!
What follows comes from a current Molpro(Version 98.1) run, where
a TS is being searched using:
optg;root,2
method,QSD,NUMHES,1,1
OPTION,IDIR=0
----------------------------------------------------------------------------
Quadratic Steepest Descent - Transition State Search
In QSD: Caution, approaching trap region, itrap = 3
In QSD: Recalculating Hessian.
In QSD: A trap region is reached: Choose another initial point
------------------------------------------------------------------------------
Should i stop the geometry optimization right now and "Choose another
initial point"? or this is an internal and i can sit, wait and hope ?
Thanks in advance,
Jorge
