CFH triple resonance probe
NMR(Nuclear Magnetic Resonance Spectrometer)



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.
