摘要

Magneto-optic measurements on spectral holes in the Q band of zinc phthalocyanine and zinc tetrabenzoporphyrin are reported. Detailed modelling of the changes in hole shape in the magnetic field requires the inclusion of a broad distribution of crystal-field splittings and a Ham factor of 0.52±0.03. Magnetic circular dichroism (MCD) spectra are also reported for spectral holes in zinc phthalocyanine and zinc tetrabenzoporphyrin. The wavelength dependence of the hole MCD gives insight into the distribution of the crystal-field split levels of the excited state. Modelling of the hole MCD shapes enables a number of factors contributing to the hole MCD shape to be identified.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
