Journal ArticleDOI
Femtosecond Time-Resolved UV−Visible Absorption Spectroscopy of trans-Azobenzene in Solution
TL;DR: In this paper, the authors used femtosecond time-resolved UV−visible absorption spectroscopy to study the UV photochemistry of trans-azobenzene (t-AB) in solution at 30 °C.
Journal ArticleDOI
Photoisomerization of a Capped Azobenzene in Solution Probed by Ultrafast Time-Resolved Electronic Absorption Spectroscopy
TL;DR: In this article, the photochemistry of trans-azobenzene and trans-1, a derivative in which trans-enzene is capped by an azacrown ether, on UV excitation to the S2(ππ*) state was studied.
Journal ArticleDOI
Vibrational mode-selective effects in the picosecond time-resolved resonance Raman spectrum of singlet excited trans-stilbene
TL;DR: In this paper, the authors obtained the time-resolved resonance Raman spectra of singlet excited trans-stilbene using several photolysis (pump) and Raman excitation (probe) wavelengths.
Journal ArticleDOI

TL;DR: The perchlorate of 2-{2-[4-(13-aza-1,4,7,10-tetroxa-13-cyclopentadecyl)phenyl]ethenyl}-3-ethylbenzothiazolium (3) has been synthesised and its structure determined in the crystalline state by X-ray diffraction and in solution in acetonitrile by 1H NMR methods as mentioned in this paper.
Journal ArticleDOI
A comparative study of the allomerization reaction of chlorophyll a and bacteriochlorophyll a
TL;DR: In this article, a combined spectroscopic and chromatographic approach has been employed to study the products of allomerization of chlorophyll a (chl a), bacteriochlorophyll b (bchl A) and bacterioviridin (bvir) under a variety of conditions.
