| Research Abstract |
1.We could record a fairly well stabilized picosecond transient absorption spectrum by a combination of a dual linear image sensor with a single polychromator. Also, the S/N ratio was much improved.
2.The intramolecular geminate recmbination kinetics of oxymyoglobin and carbonmonoxy hemoglobin are studied as a functions of solvent composition and temperature at pH 7.0.
3.We observed the formation of an exciplex or free radical ions upon excitation of 9,10-dibromoanthracene in solvents containing triethylamine.
4.Fluorescence spectra due to the lowest singlet states and triplet-triplet absorption spectra due to the lowest triplet states of 9-bromoanthracene and 9,10-dibromoanthracene have been measured in 3-methylpentane and EPA at various temperature.
5.We measured the intracomplex electron transfer upon direct excitation of a ground state complex of benzophenone with 2,5-dimethy1-2,4-hexadiene.
6.We studied the formation and decay of intermediates for the novel photo-chemistry of sterically strained [6]-1,4-cyclophaneanthraquinone.
