(color online) Distance–time curves of the four backbone HB donor–acceptor distances in one typical MD trajectory with docked NL. HB4 is highly stable with (red) Å. HB1 (black) is highly unstable. The regions where HB2 is broken (i.e., (blue) Å) are always contained in the regions where HB1 is broken.
