Singlet−Triplet and Triplet−Triplet Interactions in Conjugated Polymer Single Molecules
The Journal of Physical Chemistry B, 2005Single molecule fluorescence correlation spectroscopy has been used to investigate the photodynamics of isolated single multichromophoric polymer chains of the conjugated polymers MEH-PPV and F8BT on the microsecond to millisecond time scale. The experimental results (and associated kinetic modeling) demonstrate that (i) triplet exciton pairs undergo ...

Australian and New Zealand Journal of Obstetrics and Gynaecology, 1973
Summary: Five triplet pregnancies are described. None of these terminated prematurely. The perinatal mortality was 33%, while the sex ratio was 150:100. There was one set of conjoined twins. The literature on triplet pregnancy is reviewed and the incidence, aetiology, diagnosis, complications and management are discussed.

Obstetrical & Gynecological Survey, 1978
SummaryA series of 14 triplet pregnancies has been analyzed. The older triplet mother had a better chance of fetal survival than the younger mother. Parity did not appear to have much effect on fetal survival but the maturity of the infants at birth had more influence than did birth weight, on their survival.

Triplet-triplet excitation in helium
Physical Review A, 1980Differential cross sections for the electron impact excitation from the metastable 2 $^{3}\mathrm{S}$ state to the 3 $^{3}\mathrm{S}$ state of helium, at impact energies 50 to 500 eV, are calculated in the two-potential model and the modified Born approximation using Coulomb waves with a screened nuclear charge.

Triplet—Triplet Transitions in Naphthalene
The Journal of Chemical Physics, 1967A Pariser—Parr type CI calculation has been made for the triplet—triplet transitions of naphthalene. All configurations singly and doubly excited with respect to the lowest triplet state and with an energy relative to the lowest triplet not exceeding 7.5 eV have been taken into account. The results have taken away the discrepancy between

The Approximability of Maximum Rooted Triplets Consistency with Fan Triplets and Forbidden Triplets
2015The maximum rooted resolved triplets consistency problem takes as input a set \(\mathcal {R}\) of resolved triplets and asks for a rooted phylogenetic tree that is consistent with the maximum number of elements in \(\mathcal {R}\). This paper studies the polynomial-time approximability of a generalization of the problem where in addition to resolved ...

Triplet-Triplet Spectroscopy of Polyacenes
The Journal of Chemical Physics, 1972Complete triplet—triplet absorption spectra (2000–10000 Å) were measured in alcoholic solution at 113°K with naphthalene, anthracene, tetracene, and a few methylated derivatives. Several new bands were observed. Calculations of the higher ππ* triplet states energies with the LCAO—MO—SCF Pariser—Parr—Pople method were improved by the use of large ...

The Journal of Physical Chemistry B, 2020
Activatable triplet photosensitization refers to a photosentization process which can be turned on/off easily by external stimulus. Activatable triplet photosensitizations are normally achieved by interfering with the singlet excited state before the intersystem cross process (ISC), i.e., the formation process of triplet states of sensitizer.

Triplet-triplet absorption of biphenyl
Chemical Physics Letters, 1970Abstract Biphenyl in a cooled alcoholic solution shows structured TT absorption bands, weak in the visible and strong in the UV with a maximum at 3700A and an ∈ τ = 50 000 litre mole −1 cm −1 . Calculations using the PPP SCF method with a large configuration interaction are done using a planar model.
