Electronic spectroscopy, stimulated emission and persistent spectral hole-burning of cryogenic nitrogen matrices doped with tetrabenzoporphin
This paper deal with our on-going work on the electronic spectroscopy of tetrapyrrole molecules embedded in
 cryogenic hosts. Under nanosecond laser excitation of the free-base tetrabenzoporphin molecules in a nitrogen
 matrix at 8 K, increasing the laser pulse energy results in esse...

| description | This paper deal with our on-going work on the electronic spectroscopy of tetrapyrrole molecules embedded in
cryogenic hosts. Under nanosecond laser excitation of the free-base tetrabenzoporphin molecules in a nitrogen
matrix at 8 K, increasing the laser pulse energy results in essential enhancement of the intensity of one or several
vibronic emission lines to take place in the fine-structure fluorescence spectrum. The observed intense monochromatic
radiation possesses characteristics of stimulated radiation being realized as a result of a transition from
the purely electronic S₁ level to a vibrational sublevel of the S₀ state, corresponding to excitation of stretching C–C
vibrations of the tetrapyrrole methane bridges. We also report on persistent spectral hole-burning effects. The
analysis of the holes and antiholes formation gives some insight on the photochemical properties of
tetrabenzoporphin in a nitrogen matrix.
