The asymptotic tails of the probability distributions of thermodynamic
quantities convey important information about the physics of nanoscopic systems
driven out of equilibrium. We apply a recently proposed method to analytically
determine the asymptotics of work distributions in Langevin systems to an
one-dimensional model of single-molecule force spectroscopy. The results are in
excellent agreement with numerical simulations, even in the centre of the
distributions. We compare our findings with a recent proposal for an universal
form of the asymptotics of work distributions in single-molecule experiments.Comment: 10 pages, 8 figures, accepted for publication in Physica Script
