Measurements of the probability of pion capture by hydrogen provide information on the properties of the chemical bond of hydrogen in molecules. This is demonstrated in the examples of the temperature dependence of pion capture in hydrogen-bonded liquids and of the influence of the position of the hydrogen atom in molecules. For the proper analysis and interpretation of the pion capture data we studied the effects of pion transfer from pΠ- to heavier atoms. Measurements were made in H2 + D2 mixtures and in alcohols. Together with the information available on the muon capture and cascade processes, the pion transfer results could be used for understanding muon transfer and, in particular, to estimate the parameter q1s in muon catalysed fusion.
