VCD Studies on Chiral Characters of Metal Complex Oligomers
Abstract
:1. Introduction
- The VCD spectrum typically contains many well resolved vibrational bands, whereas ECD tends to show fairly broad band contour. This makes VCD assignment considerably more conclusive than ECD.
- Most of 3N-6 normal vibrations, which are all well resolved as stated above, are obtained from a single measurement and can be utilized to analyze the chiral character in the molecular vibrations of a given molecule.
- The DFT modeling of VCD spectra in the ground electronic state is more reliable than for ECD. Moreover the program is commercially available.
