AMMMRL:
We are buried in the complex process of relocating a DSX300 Ultrashield WB
magnet to another lab. Its current location is next to another magnet (~20'
away) which is an unshielded 400 MHz WB. The operators of this solids
instrument are concerned with the de-energizing of the DSX300 and its impact
on their spectrometer frequency. My inclination is to assume that the small
changes in field 20' away after or during the de-energizing are too small to
discern in most solids spectra. My curiosity is raised as to how to
calculate the effective frequency difference (and therefore chemical shift)
which may be induced at the static magnet (400MHz) by the change in fringe
fields (from X to zero) of the magnet being de-energized?
All comments and ideas are welcome!
Thanks,
Tanya
