摘要：
Theory for treating a two-level electronic system in superfluid helium is described. Numerical density functional theory calculations in 3-D are then used to calculate electronic absorption spectra for both spherical and angularly anisotropic chromophores. The results can be used in rationalizing the experimentally observed absorption spectra in small helium droplets. It is shown that anisotropic with the liquid does not lead to considerable changes in the linear absorption spectrum when compared to a purely spherical case.
