In Mnova, open the fid file and process it. Steps to Remove/Reduce the Broad Background Signal with Processing 1. The FID before processing and applying either linear prediction (LP) of the initial points before FT orĪ large first-order linear phase correction to remove phase distortion and rolling. This plugin is selected by default during installation of Mnova and we strongly recommend that you keep it in this way. The processing steps include left-shifting (discarding initial points) Signals coming from a normal NMR tube and possibly the glass insert of the probe. Relatively sharp and strong 11B signals from the sample sit on top of the broad background The following are the steps to remove the broad background signal during processing. ![]() One approach is to use a spin echo (90-180-Acq) with aĭelay in-between the pulses to wait for the broad signal to die out before data collection.īut, the proper NMR tube above remains the top option for removing most of the broad background. In Acquisition panel, or with the two cursor lines shown to enclose the region, enter movesw in the command line, then recollect the data.Įxperimental methods that help mitigate this problem to some extent. The two blue lines indicate a proper window size (under Acquisition) to enclose the entire broad signal. ![]()
