19F - 1H HOESY Experiment
Many of you use proton NOESY spectra to establish whether or not two types of protons are close to one another in space. The same type of experiment is also possible between nuclei of different isotopes. This technique is called HOESY (Heteronuclear Overhauser Effect SpectroscopY) and can be used to assess the spatial proximity between 2 heteronuclei. Below is an example of a 19F detected 19F - 1H HOESY spectrum of a sugar. (sample courtesy of Jennifer Chaytor)

What pulse sequence do you use?
I used a slightly modified version of the one given in the Bruker pulse program library.
