<P>Dear Users,</P>
<P>I am unclear on the force (4.4) in page 50 of Gromacs manual. </P>
<P>The force (4.4) derived from L-J potential (4.3) has missed one rij^(-1).</P>
<P>Therefore the fist item in (4.4) should be rij^(-13) and </P>
<P>the 2nd item should rij^(-7).</P>
<P>Is it right?</P>
<P>Please advise.</P>
<P>Regards,</P>
<P>Albert</P>
