One-bond coupling constants (1hJX-H) are greater than two-bond couplings (2hJX-X) in complexes with symmetric hydrogen-bonds, but 1JN-H is greater than 2hJN-N which is greater than 1hJN-H for nonsymmetric hydrogen bonds. When reduced coupling constants are used for comparison, 2hKX-X ...
There is evidence from theory and experiment to suggest that the race for multinuclear complexes with higher total spin might not necessarily be fruitful as a strategy for maximizing the magnetic relaxation barrier. Instead, we propose that more effort should be directed in understanding the ...
