Excited Triplet and Reduced Forms of CM
نویسنده
چکیده
The triplet excited state behavior of c84 has been probed by the triplet-triplet energy transfer method using pulse radiolytically generated biphenyl triplets in benzene. The triplet excited state has a weak absorption in the UV (difference absorption maxima at 3 10 and 345 nm) but no significant absorption in the visible. The rate constants for energy transfer from 3BP* and 3C60* are 4 x lo9 and 4.7 x IO9 M-' s-l, respectively. Triplet excited state properties of 3c84* are compared with other fullerenes. A photocatalytic method has also been successfully employed to reduce c 8 4 in a UV-irradiated colloidal Ti02 suspension.

The interpretation of the ultrafast luminescence decay in [Re(Br(CO)3(N^N)] complexes as a new group of chromophoric imidazo[4,5-f]-1,10-phenanthroline ligands, including 1,2-dimethoxy benzene, tert-butyl benzene (L4) and 1,2,3-trimethoxy benzene, tert-butyl benzene (L6), was studied. Fac-[Re(Br(CO)3L4 and L6] with different aryl groups were calculated in singlet and triplet excited states. The...
متن کاملState-resolved dissociation dynamics of triplet acetaldehyde near the dissociation threshold to form CH31HCO
We studied the state-resolved dynamics of S1 acetaldehyde to product channels with quantum-beat spectroscopy. Two bands near the threshold of dissociation to radical products CH31HCO in a supersonic jet, displaying most quantum-beat features, are recorded with resolution 0.025 cm. Evaluated on the basis of a simple asymmetric rotor, the origins of these two bands 140 150 1 and another denoted #...
متن کاملLifetimes of the lowest triplet state of ozone by intracavity laser absorption spectroscopy
High resolution spectra (0.014 cm -1 ) of 0 3 of the highly structured first two members of the Wulf progression in the near-infrared spectral range (9100-10200 cm -j ) have been measured by intracavity laser absorption spectroscopy (ICLAS). A preliminary analysis of the rotational structure confirmed previous assignments for the lowest excited 3A 2 (triplet) state. However, the linewidths of t...
متن کاملDavydov splitting in triplet excitons of tetracene single crystals
This work reports room temperature Davydov splitting in triplet transitions Tn ← T1 of tetracene single crystals. This was observed through femtosecond transient absorption spectroscopy with polarized ‖ b and ⊥ b probing on the (ab) face of the 300 nm thick crystal. A Davydov splitting of 0.04 eV (286 cm−1) was obtained on an excited state absorption signal ascribed to triplet excitons in Birec...

The dissociating states of the triplet–excited CO–He complex are studied by means of scattering calculations on ab initio diabatic potential energy surfaces produced in the preceding paper ~Paper I!. With the aid of an effective transition dipole function and the bound states of the CO–He complex in the ground singlet state we obtain the photoabsorption cross section as a function of the excita...
