Abstract: | Site-selection spectroscopy of free-base bacteriochlorin (7,8,17,18-tetrahydroporphin) in n-hexane, n-octane and n-decane at 4.2 K are reported. The vibrational frequencies of the ground state, and first and second excited singlet states were determined from the fluorescence and excitation spectra. Low-frequency modes were observed, from which the angle of reorientation of the Molecule upon excitation is estimated (< 1.5°). |
