Dear all, I want to calculate the lifetime of one hydrogen bond. I used g_hbond to do this. Here is the out put:
   Hydrogen bond thermodynamics at T = 298.15 K
--------------------------------------------------
Type      Rate (1/ps)  Time (ps)  DG (kJ/mol)
Forward        -0.001   -1750.289    -666.000
Backward       -0.001   -930.928    -666.000
One-way         0.000   6622.058      26.338
Integral        0.001    739.899      20.905
Relaxation      0.778      1.286       5.152

Which is the lifetime of the hydrogen bond? What does the "Forward", "Backward" etc. mean?
