Area of Science:
- Computational Chemistry
- Spectroscopy
Background:
- Advancements in computing power enable larger and more complex vibrational circular dichroism (VCD) calculations.
- Analyzing the resulting VCD spectra can be challenging due to their complexity.
Purpose of the Study:
- To introduce VCDtools, a graphical user interface (GUI) implemented in the Amsterdam Density Functional (ADF) software package.
- To provide a user-friendly tool for the analysis of VCD spectra.
Main Methods:
- Implementation of VCDtools with a GUI in the ADF software.
- Utilizing generalized coupled oscillator analysis methods.
- Visualizing atomic electric and magnetic transition dipole moments.
Main Results:
