Transmit. Coil. Liquid-phase proton FT-NMR spectroscopy. To make an NMR signal you put a coil of wire near the aligned protons. *click* By sending a brief radio-frequency pulse into the coil to can create a varying magnetic field that has the effect of tipping the protons over so they are now perpendicular to the magnetic field.

Lecture 5 Physics and Astronomy Physics and Astronomy

Newtonian/Galilean Relativity If Newton’s Laws of Motion are valid in one (inertial) reference frame, they are also valid in any other reference frame in uniform (not accelerated) motion with respect to the first. This is a result of the fact that Newton’s 2nd Law: F = ma = m (d2r/dt2) involves a 2nd time derivative of r.
