Dear BUM'ers,
Recently, we upgraded XWinNmr from version 2.6 to 3.0. After this we had to
change the spectrometers base frequency from 600.13 to 600.087 MHz!
When we tried the lineshape test sample, the acetone signal appeared at
~-72 ppm. The only way we could fix this shift was by configuring the
spectrometer to a lower base frequency. Installation from scratch didn't
solve the problem.
Our instrument is an Avance DRX-600 with SGI and Irix 6.5.
Does anyone have a clue of what had happened?
Thank in advance! /Nils Nyberg
