The job fails because there are more resonance structures than what
the
computer memory can cope with. I've increased the alloted memory to
the
maximum, and it crashes still. But I don't need all these structures!
I
only want to look at the major ones. Is there a way of increasing the
threshold, so the program ignores the structures that contribute less
than
so-and-so, and thus saves on memory? And if it's not possible, any
suggestions on what I might try to find the major structures anyway?
You must up the delocalisation threshold. Since the default is 1
kcal/mol you could try something like NRTTHR=10 or 20 and then go down
as you please to get more resonance structures.
Cheers,
Nuno
