The atom is placed in a static magnetic field and a perpendicular rotating magnetic field. We present a classical treatment in here. ==Theory== When only the static magnetic field (B0) is turned on, the spin will precess around it with Larmor frequency ν0 and the corresponding angular frequency is ω0. According to mechanics, the equation of motion of the spin J is: :: $\backslash frac\; =\; \backslash vec\; \backslash times\; \backslash vec$ :: $\backslash vec\; =\; g\; \backslash frac\; \backslash vec\; =\; \backslash gamma\; \backslash vec$ where μ is the magnetic moment. g is g-factor, which is dimensionless and reflecting the environmental effect on the spin. Solving gives the angular frequency (Larmor frequency) with the magnetic field pointing on z-axis: :: $\backslash omega\_0\; =\; -\; \backslash frac\; B\_0$ The minus sign is necessary. it reflects that the J is rotating in left-hand when the thumb is pointing as the H field. when turned on the rotating magnetic field (BR), with angular frequency ω. In the rotating frame of the rotating field, the equation of motion is: :: $\backslash frac\; =\; \backslash frac\; -\; \backslash vec\; \backslash times\; \backslash omega$ or :: $\backslash frac\; =\; \backslash frac\; \backslash vec\; \backslash times\; (\backslash vec\; +\; \backslash vec)\; -\; \backslash vec\; \backslash times\; \backslash omega$ if $\backslash frac\; B\_0\; =\; \backslash omega$, the static field was cancelled, and only the "sleeping" rotation frame. and the spin is now precess around HR with angular frequency Rabi frequency :: $\backslash omega\_R\; =\; \backslash frac\; H\_R$ Since the rotating field is perpendicular to the static field. the spin in rotating fame is now able to flip between up and down. by sweeping ωR, one can obtain a maximum flipping and determine the magnetic moment. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rabi resonance method」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
