摘要: We studied the photoinduced ionic to neutral phase transition in tetrathiafulvalene-p-chloranil (TTF-CA) using time-resolved infrared vibrational spectroscopy. By monitoring charge sensitive b1uν10 band of CA after photoexcitation by a 1.55 eV pulse, we found that N-phase has same thermal equilibrium and there is no variation during transition. also grows through at least two steps over 300 ps.
