Calculation
- IR and Raman spectra and its vibrational mode are calculated by Firefly QC package [1], which is partially based on the GAMESS (US) [2] source code.
- The B3LYP functional with 6-311+G(d,p) basis set is used.
- Horizontal axis of the spectra are corrected by wavenumber-linear scaling (WLS) [3]. The scaling falctor of WLS is sWLS = α - 10-5 β ν.
- Parameters of the compound are refferd to PubChem [4].
