張量演算子對史托克效應的應用

Abstract

The expressions of the energy levels and line strengths of the Stark effect for both symmetric and asymmetric rotors have been derived by employing the spherical tensor operator and first-order rotational representations.The application of the Wigner-Eckart theorem have been briefly discussed.The magnitudes of the energy matrix elements for first and second-orders and line strengths of J up to 4 of the symmetric tops have been tabulated.Some experimental measurements have been discussed.
