Oscillator Strengths and Transition Dipole Moments from a Simplified Equation-of-Motion Coupled Cluster Formalism within the Frozen-Pair Approximation

This paper derives working equations for transition density matrices, dipole moments, and oscillator strengths within the EOM-frozen-pair coupled-cluster framework (EOM-fpCCSD and EOM-ptCCSD) using approximations that avoid solving Λ\Lambda equations and calculating left eigenvectors, demonstrating that these models yield improved excited-state properties compared to standard EOM-CCSD.
