... • Each signal has its own T1, and it is dependent on magnetic field strength • When a sample is placed into a magnetic field it takes some time for the bulk magnetisation vector to form • the time required to reach thermal equilibrium is at least 5 x T1 • For quantitative NMR we must wait at least 5 ...

... The voltage drop across the diode is v1 = VS, and the diode is turned off (an open circuit). Also, i11 = VS/R11. Case 3: At t = 0-, v1 = VS, where VS > 0V. Then at time t = 0, the interface logic switches and presents a high impedance to the rest of the circuit. At time At t = 0+, the current i11 = ...

Microstructured Resonators for Electron Spin Resonance
... For all these structures, at least one dimension is proportional to the wavelength of the microwave. This limitation was always avoided in the case of nuclear magnetic resonance (NMR), where typical wavelengths were several meters at the frequencies used in early experiments. In this case, the reson ...

A moving electric charge is surrounded by a magnetic field.
... Since a charged particle moving through a magnetic field experiences a deflecting force, a current of charged particles moving through a magnetic field also experiences a deflecting force. ...
