Comparative Vibrational Spectroscopic Studies Between Nickel, Zinc Tetraphenylporphyrins and Tetraphenylchlorins

摘要

The infrared and resonance Raman spectra are reported for nickel and zinc tetraphenylchlorins. It is found that the IR and RR spectra become more complicated compared with the corresponding porphyrin analogs due to the symmetry changes. Some vibrational parameters like the core size and the symmetry change are examined in accordance with vibrational spectra of other type of chlorins.
