史托克及核回偶矩之合效應

Abstract

The application of the Wigner-Eckart theorem and the first-order rotational representations have been used to derive the expressions of the energy matrix elements for the first and second-order perturbations and the relative intensities of the Stark effect with one nuclear quadrupole moment for the weak electric field case.The numerical values of the exact energy elements with the elgenvectors of the first-order and the second-order energy elements for j≦4 and I≦3 have been calculated. The comparisons of the relative intensities for the ammonia inversion spectrum between the previous method and the treatment presented here have been shown.The relative intensities in terms of 3j symbols for the symmetric rotors have been shown in Appendix. Some calcullated values have been tabulated for illustration.
