Converting NMR Pulses represented as kHz to usable format in Bruker Topspin 3+

Researchers tend to use the units of kHz to represent the power of decoupling or shaped pulses in research papers. The reason for the use of this unit is to easily transfer the pulse-widths & power-levels used in the experiment from one spectrometer to another, as one can back calculate the pulse-widths & power-levels as …

Splitting Pseudo-3D experiments into series of 2Ds in Topspin 3+

Interleaved experiments are easy to run as pseudo 3D experiments. A detailed method to design NMR experiments in Topspin 3+ is described previously. While running the experiments or after the run the user may have to split the data into their respective 2Ds to evaluate the results. This can be done easily by using “xfb” …

Designing interleaved experiment in Bruker Topspin 3+

Interleaved NMR experiments are often used to collect relaxation dispersion, zz-exchange, CPMG relaxation and T1/T2/NOE relaxation etc. This is often done to minimize the effect of degradation of sample, precipitation and aggregation over time on individual experiments. These aforementioned experiments can be done as a bunch of 2D experiments queued one after another, but the …
