We have three samples , 31P{19F} we would like to have run by anyone
capable of doing 19F decoupling. We are willing to negotiate a price.
Coupling ranges up to 1000 hz. Compounds are:
N3P3F4(OPH)2 N3P3F3(OPH)3 N3P3F6 (used to check decoupling
quality)
31P spectra a complex 2nd order triplet of multiplets.......Decoupled
31P spectrum should be a singlet.
Chemical shifts range up to 30ppm for 31P . For 19F the shifts are -60
to -90 relative to (4- Fluorobenzaldehyde)
Anyone help? Our ARX 500 doesnt seem to have the power to do the job.
Thanks
Jim
