preparation of the chloro- and bromo-trimethylammonium cations as a series of salts including the perchlorates and fluorosulphates. The vibrational and n.q.r. spectra are reported and discussed in relation to the bonding in the ions. Halogen and interhalogen adducts of trimethylamine have also been studied, and it is concluded that halogenotrimethylammonium cations are not present in these species.
