# @kalika/spectroscopy-extended

Auxiliary spectroscopies for Kalika (Phase 124): UV-Vis absorption and
oscillator strengths, photoluminescence from the configuration-coordinate model
(Huang-Rhys, ZPL, Stokes shift, radiative rate, temperature dependence), X-ray
emission (Kalpha/Kbeta, valence-to-core, Kbeta mainline spin analysis), resonant
inelastic X-ray scattering (Kramers-Heisenberg, RIXS maps, dd excitations), EPR
(g-tensor, hyperfine, zero-field splitting, powder spectrum), and Compton
profiles / positron annihilation lifetimes.
