NMR Panopticum: Interference with Neighbor

A neighboring NMR spectrometer operating at the same field strength and running proton-decoupled carbon-13 NMR causes decoupler sidebands in the proton spectrum. The magnets are 6-7 m apart, the consoles about 4-5 m.

Possible solutions:

• For various reasons, this is not bothering us much, therefore we live with it.
• One solution could be to alter the operating frequencies of both spectrometers by cranking up one and lowering the other; this is limited by the range of the FIELD setting on the BSMS. (Actually, we tried this approach, but the separation was not sufficient.)
