洛仑兹线型的微分自消卷积

DERIVATIVE SELF-DECONVOLUTION OF LORENTZIAN LINESHAPE

用简捷的方法,在理论上获得了洛仑兹线型的微分消卷积算符,并给出了实用的消卷积算符。借助样条函数,利用所获得的算符可分辨出Eu^(3+)的~7F_0→~5D_1在水溶液中的谱带结构,提高了原始光谱的分辨率。

The derivative deconvolution operator of the Lorentzian lineshape has been got in theory. Furthermore, a practical deconvolution operator of the Lorentzian lineshape has been obtained, that can be directly applied to the experimental spectrum. Using a spline function, the absorption band structures for the ~7F_0→~5D_1 transition of Eu^(3+) ions in aqueous solution are resolved by the proposed theory, and the spectral resolution is improved.
