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 s_WLS = α - 10^-5 β ν.
• Parameters of the compound are refferd to PubChem [4].
