The solvent shifts of haloformic protons, (Cl3CH, Br3CH, I3CH), have been measured in 24 n‐electron donor solvents consisting of halogenated hydrocarbons, esters, ketones, ethers and amines. Deviations of ΔBr and Δ1 from linear dependence with ΔCl are indicative of the presence of halogen bond formation competitive with hydrogen bonding interactions. Bromoform interacts predominantly by hydrogen bonding, halogen bonding being detected to a small extent in chlorinated hydrocarbons and amines. Iodoform shows halogen bonding interactions which increase in relative importance to hydrogen bonding with solvent basicity. Halogen bonding is predominant for solutions of iodoform in amines.
