چکیده انگلیسی
The application of point-group coupling coefficients to the modeling of fNâfNâ1d transitions is discussed. There are several possible coupling schemes for the states of the fNâ1d configuration. Formulae for matrix elements of the Hamiltonian for the fNâ1d configuration and the relative line strengths for fNâfNâ1d transitions are derived. As an example, the f-d absorption spectrum of the crystal Yb2+: SrCl2 is calculated using coupling coefficients based on the software developed by Butler and co-workers, which makes use of the Racah-Wigner calculus. The advantages and disadvantages of various coupling schemes are demonstrated. These coupling schemes are related to the simple model for f-d transitions.
