The asymptotic tails of the probability distributions of thermodynamicquantities convey important information about the physics of nanoscopic systemsdriven out of equilibrium. We apply a recently proposed method to analyticallydetermine the asymptotics of work distributions in Langevin systems to anone-dimensional model of single-molecule force spectroscopy. The results are inexcellent agreement with numerical simulations, even in the centre of thedistributions. We compare our findings with a recent proposal for an universalform of the asymptotics of work distributions in single-molecule experiments.
