Journal ArticleDOI
The Benzophenone S1(n,π*) → T1(n,π*) States Intersystem Crossing Reinvestigated by Ultrafast Absorption Spectroscopy and Multivariate Curve Resolution
Stéphane Aloïse,Cyril Ruckebusch,Lionel Blanchet,Julien Réhault,Guy Buntinx,Jean-Pierre Huvenne +5 more
TL;DR: It is proposed that the benzophenone intermediate species is a T(1)(n,pi*) high vibrational level in interaction with T(2)(pi, pi*) state, and investigated 4-methoxybenzophenone.
Journal ArticleDOI
Investigation of ultrafast photoinduced processes for salicylidene aniline in solution and gas phase: toward a general photo-dynamical scheme.
Michel Sliwa,N. Mouton,Cyril Ruckebusch,Lionel Poisson,Abdenacer Idrissi,Stéphane Aloïse,Ludovic Potier,Julien Dubois,Olivier Poizat,Guy Buntinx +9 more
TL;DR: A general photoinduced mechanism for salicylidene aniline is drawn and it shows that ESIPT and rotation to the twisted-enol for SAOH occur within 100 fs, as predicted by recent quantum dynamical simulations, with an efficiency ratio dependent on the excitation wavelength.
Journal ArticleDOI
Subpicosecond transient absorption analysis of the photophysics of 2,2'-bipyridine and 4,4'-bipyridine in solution
TL;DR: The transient absorption spectra of 2,2'bipyridine (22BPY) and 4,4'-biprinitrioptaridine (44BPY), following femtosecond excitation at 266 nm in a series of organic solvents have been measured in the 300−670-nm wavelength range with subpicosecond time resolution as discussed by the authors.
Journal ArticleDOI
Gas-phase dynamics of spiropyran and spirooxazine molecules.
TL;DR: The gas-phase dynamics of two classes of photochromic molecules, three spiropyrans and one spirooxazine, have been investigated here using both time-resolved mass spectrometry and photoelectron spectroscopy approaches, and a sequential photoisomerization mechanism is proposed.
Journal ArticleDOI
Photochemistry of 2-naphthoyl azide. An ultrafast time-resolved UV-vis and IR spectroscopic and computational study.
Jacek Kubicki,Yunlong Zhang,Shubham Vyas,Gotard Burdzinski,Hoi Ling Luk,Jin Wang,Jiadan Xue,Huo Lei Peng,Elena A. Pritchina,Michel Sliwa,Guy Buntinx,Nina P. Gritsan,Christopher M. Hadad,Matthew S. Platz +13 more
TL;DR: The photochemistry of 2-naphthoyl azide was studied in various solvents by femtosecond time-resolved transient absorption spectroscopy with IR and UV-vis detection and results correlate with the results of electron density difference calculations that predict nitrene formation from the higher-energy singlet excited states, in addition to the S(1) state.
