Sir
If I write the uncertainty as is it, will be like (-6.45+_10.39) the
uncertainty greater than value. Is it ok?
Is uncertainty in T of delta TS available.?
In some papers I see they include uncertainty (of delta G) also. but its
very small value; less that one.
I asked about uncertainty term in hbond distance: its another doubt. Is
anyone familiar with it. Its a review question I got. I don't understand
how should I comment it.
Thanking you
