In the case of oligosaccharides, each sugar residue is an isolated spin system, so it is possible to differentiate all the protons of a specific sugar residue.
22.
The satellite performed nominally, except for the spin system, which failed to maintain 60 rpm ( at spin rates below 10 rpm data reduction became difficult ).
23.
However, it is still an open question whether there is a local dynamics that does not suffer from critical slowing down in spin systems like the Ising model.
24.
Since the energy flow is predominantly within the spin system, it makes sense to think of a spin temperature that is distinct from the temperature associated to other modes.
25.
The existence of low-energy excitations is related to the fact that in the absence of an external field, the spin system has an infinite number of degenerate ground states with infinitesimally different spin orientations.
26.
Yo-yo de-spin systems are commonly used on NASA sub-orbital sounding rocket flights, as the vehicles are spin stabilized through ascent and have minimal flight time for roll cancellation using the payload's attitude control system.
27.
On the other hand, when the electron spin system is in a thermal equilibrium, the polarization transfer requires continuous microwave irradiation at a frequency close to the corresponding electron paramagnetic resonance ( EPR ) frequency.
28.
It uses a system of three active nuclei ( SXI spin system ) to measure an unresolved coupling with the help of a larger coupling which is resolved in a dimension orthogonal to the small coupling.
29.
The'pump'beam is designed to excite or perturb the sample from equilibrium, it is very intense designed to create highly non-equilibrium conditions within the sample material, exciting the electron, and thereby subsequently the phonon and the spin system.
30.
Three active nuclei are needed ( SXI spin system ) and the pulse sequence must be able to transfer magnetization from I to S without changing the spin state of X, otherwise the ECOSY pattern will vanish.
