In gromacs ,on using -life option we get the following answer

Type Rate (1/ps) Time (ps) DG (kJ/mol) Chi^2

Forward 0.149      6.692    9.313 0.00998919

Backward 0.589   1.699    5.894

One-way 0.126    7.910    9.730

Integral 0.055     18.056   11.789

Relaxation 0.091 11.019  10.557

HB lifetime = 0.85 ps

Note that the lifetime obtained in this manner is close to useless

Use the -ac option instead and check the Forward lifetime

 So what should be the actual hydrogen bond lifetime? The uninterrupted hydrogen bond lifetime should be 0.85ps or 6.69(forward lifetime)? What about structural reorganisation time? Is it same as relaxation time defined here?
