Summary

CFH triple resonance probe can measure 1H magnetic resonance with decoupling of 19F and 13C magnetic resonance with decoupling of 1H and 19F (13C{1H, 19F} ) simultaneously.
As a result, structures of fluorinated materials can be identified more in detail and more precisely.
A variety of 2D experiments and all combinations of 1H, 19F and 13C are available, including 19F {1H}, 1H {19F}, 13C {19F}, etc.

<Difficulties in NMR measurement of fluorinated materials>

・The large coupling constant of 13C-19F and 1H-19F
→Complicated signal patterns Lower ratio of signal-to-noise
・Resonance frequency of 19F is close to 1H
→Interference with a radio wave
・Range of Chemical shift of 19F is wide
→Lower precision caused by the lack of decoupling band

<Merits of CFH triple resonance probe>

・Independent channels for 1H and 19F
→Excitation and irradiation of 1H,19F without interference with a radio wave
・Various kinds of decoupling pulses
 Multi-site decoupling
Composite pulse decoupling
MPFn, WURST etc.

→Super broadband decoupling is possible Various kinds of combinations like 1H{19F}, 13C{1H,19F}, 1H-19F(2D) are available.
