Fig. 3. (a) Experimental (black), DFT-calculated ground state (green) and step-scan FTIR spectra (top, λ_exc = 355 nm; 0–500 ns) of VCl₃(ddpd-[D₀]) in a KBr pellet at 290 K (red) and (b) excited state FTIR spectra of VCl₃(ddpd-[D₀]) in a KBr pellet obtained from step-scan FTIR spectra (λ_exc = 355 nm; 0–500 ns) (small contributions of 3% of the respective ground state spectrum added to the step-scan spectrum) at 20 K (blue) and 290 K (red).
