Hi all,
I'm trying to set up a 19F-1H HOESY experiment on a Varian NMR system using
a dual-tuned high-band probe, where both 19F and 1H resonances are tuned
simultaneously on channel 1. The second channel is reserved for X-band nuclei,
so I need to run the entire sequence on channel 1 alone. The standard Varian
19F-1H HOESY sequence (e.g., from BioPack) uses channel 1 for 1H and channel
2 for 19F, which doesn't match my probe configuration. Has anyone successfully
modified or created a 19F-1H HOESY pulse sequence for a single-channel setup
on a Varian system? If so, could you share the pulse sequence code or parameter
settings (e.g., how to handle frequency switching between 19F and 1H on channel 1)?
Any advice on calibrating pulse widths or setting up VNMRJ parameters for this
configuration would also be greatly appreciated.
My system is with this probe is a 400 VNMRS. Thanks in advance for any help
or pointers to relevant resources!
Best, Shawn
