[gmx-users] definition of J-couplings in g_chi

[Justin A. Lemkul]

The manual will not spell everything out for you, but a little bit of background 
reading will give you the answer.  From g_chi -h:

"...
(b) The NMR 3J coupling constants from the Karplus equation.
..."

The curious individual would then probably look up what the Karplus equation is, 
and via Google search, arrive here:

http://en.wikipedia.org/wiki/Karplus_equation

The answers are out there, and if you don't know what a term or parameter means, 
Google is usually your friend.
