A novel series of hydrogen-bonded solid 1 : 1 acid-base complexes of 15 N-labeled 2,4,6-trimethylpyridine (collidine) with carboxylic acids and their hydrogen bond deuterated analogs were synthesized and studied by 1 H magic angle spinning (MAS) and 15 N cross-polarization NMR with and without MAS.
