The solvent shifts of the methylenic protond of CH 2 Cl 2 , CH 2 Br 2 and CH 2 I 2 have been measured in amines, ethers and non‐polar solvents. Correlation of the solvent shifts of the bromine and iodine compounds Δ Cl , serves as a monitor of halogen bonding interactions which are competitive with hydrogen bonding association. Amines interact with CH 2 I 2 via a halogen bond while in ethers hydrogen bonding predpminates. CH 2 Br 2 shows solute–solvent interactions identical to CH 2 Cl 2 .
