Packet 8: Tossup 20

A constant describing the interaction between two values of this quantity is determined from the dihedral angle in the Karplus equation. (15[1])J-coupling represents the interaction (15[1])between two values of this quantity, (-5[1])which returns to its equilibrium value during T1 and T2 relaxation. Applying an RF pulse “flips” states corresponding to values of this quantity in (*) NMR. In an inhomogeneous magnetic (10[1])field, this quantity took on two discrete values in the Stern-Gerlach experiment. (10[1])In orbital diagrams, values of this quantity are represented using up and down arrows. (10[1])For 10 points, name this intrinsic angular momentum of a particle. ■END■ (10[1])

ANSWER: spin angular momentum [accept spin-spin coupling or spin relaxation or spin flip or magnetic dipole moment; prompt on magnetic moment; prompt on magnetization before mentioned; prompt on just coupling before mentioned by asking “what quantity’s interaction is represented by coupling?”; do NOT accept ELECTRIC dipole moment]
