Characterization of intraligand charge transfer transitions in Pd(qol)₂, Pt(qol)₂, and Pt(qtl)₂ investigated by Shol'skii spectroscopy

Zusammenfassung

Pd(qol)₂,Pt(qol)₂ and Pt(qtl)₂ are investigated in n-octane Shpol’skii matrices at T = 1.2 K. For the first time, it is possible to obtain highly resolved phosphorescence and triplet as well as singlet excitation spectra. The corresponding excited states are assigned to intraligand charge transfer (ILCT) transitions. Their characteristic electronic and vibrational properties are studied in detail.
