    Sammanfattning : The central aim of this thesis is to derive, implement and test new methods to calculate various types of spectroscopies of compounds containing heavy elements in an aqueous environment. Methods that can target such systems have to consider the following:(i) It is crucial to take relativistic effects into account. LÄS MER

  7. 5. Derivation and application of response functions for nonlinear absorption and dichroisms

    Författare :Tobias Fahleson; Patrick Norman; Daniel Crawford; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical spectroscopy; cubic response theory; damped response theory; magnetic circular dichroism; linear birefringence; two-photon absorption; TPA; resonant-inelastic x-ray scattering; RIXS; DALTON program; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Sammanfattning : This thesis is titled ’Derivation and application of response functions for nonlinear absorption and dichroisms’ and was written by Tobias Fahleson at the Division of Theoretical Chemistry & Biology at KTH Royal Institute of Technology in Sweden. It explores and expands upon theoretical means of quantifying a number of nonlinear spectroscopies, including two-photon absorption, resonant inelastic x-ray scattering, Jones birefringence, and magnetic circular dichroism.
