Abstract

The aim of this paper is to provide a comparative study of the spectroscopic properties of Mn⁴⁺ (3d³) ion in the orthorhombic perovskites, ASnO₃ (A=Ca, Sr). The most significant parameter controlling the energy of the zero-phonon line (²E→⁴A₂ transition) is the deviation of the octahedral O-Mn-O bond angle from the ideal 90⁰ value. It is significant that despite the longer Sn⁴⁺-O^2- bond distance, the crystal field strength (10 Dq) in CaSnO₃ is higher than that of SrSnO₃. We discuss this result in relation to the perovskite crystal chemistry. Mulliken population analysis and bond order calculation are made to clarify the nature of chemical bonding in the stannate perovskites.
