The ultrafast relaxation of 2-iodotoluene has been investigated by state-selective femtosecond time-resolved mass spectrum following excitation at 266 nm,with focus on the dissociation channel.
The congestion of the vibronic states in C2 often causes perturbations in the observed spectra due to interactions between the accidently crossing rotational levels.
Asymmetrically substituted carbonyl compounds have been extensively explored experimentally and theoretically [1-2];however,full-dimensional trajectory-based nonadiabatic dynamics simulations that tre
In contrast to high fluorescent GFP proteins,the core chromophore itself,as well as the recently synthesized ortho-hydroxyl GFP analogues,is not emissive in neutral and anion forms in solution.
For the first time,the ground and lowest-lying singlet excited state geometries and dipole moments of trans-4-N,N-dimethylamino-4-nitro-stilbene (DNS) and trans-4-N,N-dimethyl-amino-4-cyanostilbene (D
ApcE(1-240) dimers with one intrinsic phycocyanobilin (PCB) chromophore in each monomer that is truncated from the core-membrane linker (ApcE) of phycobilisomes (PBS) in Nostoc sp.PCC 7120 show a shar
