Abstract	다원자분자내의 내부회전자상에 있는 자기핵은 분자의 전체회전으로 인하여 생기는 자기장뿐만 아니라 내부회전에 기인하는 자기장과도 상호작용할 수 있다. 이 논문에서는 다원자분자내의 내부회전자상에 있는 핵스핀에 대한 스핀-회전상호작용 Hamiltonian을 유도하였다. 유도된 Hamiltonian은 스핀과 전체회전간의 상호작용을 나타내는 부분 및 스핀과 내부회전간의 상호작용을 나타내는 부분과의 합으로 이루어져 있음을 밝혔다. 스핀-회전상호작용 tensor와 자기적 가리움효과 간의 관계도 또한 조사하였다. A magnetic nucleus located on an internal rotor in a polyatomic molecule can interact with the magnetic fields arising from internal rotation as well as end-over-end molecular rotation. In this paper the spin-rotation coupling Hamiltonian for a nuclear spin on a symmetrical internal rotor in a polyatomic molecule is derived. The derived spin-rotation Hamiltonian turns out to be composed of the two parts: the spin-over-all-rotation interaction and the spin-internal-rotation interaction. The relation between the spin-rotation coupling tensor and the magnetic shielding effect is also investigated.
