1 H and 15 N NMR spectra of 10 complexes exhibiting strong OHN hydrogen bonds formed by 15 N-labeled collidine and different proton donors, partially deuterated in mobile proton sites, have been observed by low-temperature NMR spectroscopy using a low-freezing CDF 3 /CDF 2 Cl mixture as polar aproti
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.
