Femtosecond to microsecond observation of the photochemical reaction of 1,2-di(quinolin-2-yl)disulfide with methyl methacrylate

“…The experimental setups and procedures used for TEAS and TVAS measurements have been described previously, [28][29][30][31][32] therefore only details specific to the present study are provided here.…”

“…The QSSQ solutions were prepared to obtain an optical density of ~0.5 OD with the 100 μm or 380 μm spacers at the 330-nm excitation wavelength (1.0 mM for TEAS and 3.8 mM for TVAS experiments). The instrument response function (IRF) was 150 fs for TEAS experiments, 9 ~300 fs for TVAS experiments at the University of Bristol, 32 and < 200 fs for TVAS experiments at RAL. 29 The pure solvents (methanol and MMA) showed transient response signals which contributed backgrounds to the recorded TEA spectra.…”

The DNA nucleobase thymine in motion – Intersystem crossing simulated with surface hopping

“…Measurements in aqueous solutions find that ISC yields are 0.004 [15] to 0.006 [16], while in chloroform the yield is 0.08 [17]. In acetonitrile the reported values range from 0.06 [16] to 0.18 [18], suggesting that ISC in thymine is solvent depen-dent and that less polar solvents enhance ISC.…”

Triplet‐Induced Lesion Formation at CpT and TpC Sites in DNA

“…While femtosecond and nanosecond‐IR techniques were used to study the singlet and the triplet reaction channel of TpT or (dT) 18 , these techniques have not been used for the investigation of the reaction dynamics of CpT and TpC. Additionally, the photophysics of individual thymine and cytosine derivatives are still the topic of current research (e.g., see refs …”

“…Additionally,t he photophysics of individual thymine and cytosine derivatives are still the topic of current research (e.g.,s ee refs. [26][27][28][29][30]), building the foundation for ad etailed understanding of photoreactions in the corresponding dipyrimidines.…”
