Blue and red shifts in F3C-H ⋯ B (B = FH, ClH, OH2, SH2 and Cl−) complexes predicted by a perturbative model

The figure in the graphical abstract shows a hydrogen-bonded complex of trifluoromethane (F3C-H) interacting with a proton acceptor (FH, ClH, OH2, SH2 or Cl−) which is represented by the green sphere.
