Watch liquid Helium boil off to gaseous state from a decommissioned 360 MHz NMR magnet. For every litre of liquid Helium, 750 litres of gaseous Helium is generated. When the Helium boils off the superconductor is no longer a superconductor and this seizes to be a magnet. Watch the steel screwdriver fall off once this […]

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

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”

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
