    • The term wavepacket is used within the one-dimensional model that only includes torsion angle as the reaction coordinate. Thus, the term wavepacket refers to the population placed on the excited state, which is distributed along the torsion coordinate. This spread along the reaction coordinate is due to the fact that finitely wide pulse spectra are used and the S0-S1 transition energy in the one-dimensional model is determined by the torsion angle of a given molecule. It should be stressed that the use of the term wavepacket in this publication does not refer to the superposition of vibrational levels

    • The absolute quantum yield of photoisomer (Φiso) following the ∼100 fs excitation pulse at a 523 nm wavelength of 1122C in methanol was determined by the following expression: Φiso, ΔA(545) exp(t/τiso)/εPH(545, ε NF(545) N A 10-3 Fhv(πd2/4)/E(1-10 -A(523, Here, ΔA(545, 1.6 × 10-3, εPH(545, 3.34 · × 104 M-1 cm-1, and εNF-(545, 1.59· × 10 4 M-1 cm-1 are the transient absorbance, and the extinction coefficients of the photoisomer and trans-isomer all at the probe wavelength 545 nm, E, 0.18 × 10-6 J and F, 1.04 are the incident excitation energy and its measured loss due to reflection off the cell front window, ΔA523, 0.17 is the sample absorbance at the excitation wavelength
