We have tested both 13C and 31P observe with 1H decoupling and the transient spikes that were observed earlier is not present anymore.\u00a0\u00a0 The hardware is working as expected and a mis-adjustment in the parameter setup is identified as the main cause of the noise.<\/p>\n
We shall keep a close watch, nevertheless.<\/p>\n
Please note that you do not need anything more than 300 ms of AQ when you run 13C or 31P with decoupling.\u00a0 The inherently large spectral resolution will afford a well resolved spectrum even with this FID length.<\/p>\n
On the other hand, increasing the acquisition time beyond this with broadband decoupling ON, will lead to probe damage.\u00a0<\/strong> Please consult one of us, when in doubt. If you are convinced that a longer FID length is needed, there are workarounds to achieve that.<\/p>\n Thank you for helping to preserve your spectrometer.<\/p>\n NMR Facility Manager<\/p>\n 2\/27\/2018<\/p>\n","protected":false},"excerpt":{"rendered":" We have tested both 13C and 31P observe with 1H decoupling and the transient spikes that were observed earlier is not present anymore.\u00a0\u00a0 The hardware is working as expected and a mis-adjustment in the parameter setup is identified as the main cause of the noise.
