Hi all:) I apologize for my simple ( or well, stupid) question: I was wondering if it is possible to run a 2D 13C19F experiment on a Bruker Avance spectrometer with BBFO probe. I was under the impression that 19F is run on the 13C channel, so its not possible.. something like this. Is this correct? Thanks!!!

Hi, Yeah it doesn't seem like 13C{19F} can be done with a BBFO 2 channel probe. - RudrakshLethbridge (Nov 16 '12 at 09:29)

Hello,

maybe you have luck, ... please look into the specifications of your Bruker probe! There are two different types of it:

BBOF and BBOF-Plus.

  • BBOF there the Flourine is on the inner coil, the X coil!
  • BBOF plus, it is the same like BBOF, but also the proton coil is tune- and match-able to fluorine on the outer coil! But only with a special cabling and filter scheme outside the HPPR! With the second one you have the chance to do this Carbon-Fluorine as HETCOR or as HSQC or HMBC.

Yours sincerely,

Uli Haunz

There's only chance for Bruker BBFO probe to tune H coil to 19F if you see the labels on RF connectors at the probe body: 2H | HF | BBF - there's a rear modification of BBFO probe (but BBFO plus is not the same, it's just BBFO with extra sensitivity) that gives you a way to measure 13C-19F correlations

If the labels are the following: 2H | H | BBF - there's no chance to tune 1H coil to 19F (for ATM probes at least)

Hi,

yes, as far as I can see it, such an experiment is not possible on a BBFO probe.

Hi, Yeah it doesn't seem like 13C{19F} can be done with a BBFO 2 channel probe, for the reason you stated.
