Liquid Structure of Acetic Acid Studied by Raman Spectroscopy and Ab Initio Molecular Orbital Calculations
TL;DR: In this article, the liquid structure of acetic acid was studied experimentally and theoretically experimentally, and theoretically, the Raman spectra were measured in the region 15−3700 cm-1.
Journal ArticleDOI
pH dependence of the fluorescence lifetime of FAD in solution and in cells.
TL;DR: P pH dependence of the fluorescence lifetime of flavin adenine dinucleotide (FAD), that is a significant cofactor exhibiting autofluorescence, has been investigated in buffer solution and in cells, and thefluorescence lifetime in HeLa cells was found to decrease with increasing intracellular pH.
Journal ArticleDOI
Application of fluorescence lifetime imaging of enhanced green fluorescent protein to intracellular pH measurements
TL;DR: It is shown that the intracellular pH of a single HeLa cell expressing the enhanced green fluorescent protein (EGFP) can be imaged using the fluorescence lifetime of EGFP, which can be interpreted in terms of the pH-dependent ionic equilibrium of the p-hydroxybenzylidene-imidazolidinone structure of the chromophore of EG FP.

TL;DR: It is found that pH in a single cell can be determined by fluorescence lifetime imaging of NADH without adding exogenous fluorescent probes, and the magnitude of the pH-induced lifetime change is higher in cells than that in buffer solution.
Journal ArticleDOI
Ultrafast excited-state dynamics in photochromic N-salicylideneaniline studied by femtosecond time-resolved REMPI spectroscopy
TL;DR: Investigation of ultrafast processes in photoexcited N-salicylideneaniline with femtosecond time-resolved resonance-enhanced multiphoton ionization spectroscopy reveals that an internal conversion to the S(1)(n,pi( *)) state of the enol form may provide opposite effect on the quantum yield of photochromic products.
