TINDOR: A triple-resonance experiment and the problem of the sign of a lone long-range coupling constant

Mostrar todas las versiones(2)

It is shown that tickling and INDOR techniques can be used jointly under certain conditions to give information unattainable by other means. These conditions are that all the transitions involved shall be connected in chain. The experiment fails if they are connected as a branch. Under these conditi...
