The caged Ca-compound DM-Nitrophen was introduced into the presynaptic terminal via a patch pipette, and
flash photolysis was applied, which elevated Ca uniformly (Fig.
Transient absorption spectra were recorded using a home-made laser
flash photolysis equipment.
Laser
Flash Photolysis. In the triplet-triplet absorption measurements, the samples were excited using the same instrumentation as described above.
A strong evidence for the presence of such an intermediate has been presented by Ahmad and Tollin [21] who studied the solvent effect on flavin electron transfer reactions using laser
flash photolysis. According to these workers the reduction of flavin triplet ([sup.3]Fl) by the substrate (amine in this case) proceeds via a dipolar intermediate in water and organic solvents and, therefore, the rate is increased with an increase in the solvent dielectric constant:
Laser
flash photolysis experiments employed the pulses from an Applied Photophysics with YAG laser (355 nm, pulse, 5 ns) and a computer controlled system.
Chemists mostly in the US discuss inorganic and bioinorganic spectroscopy, 57Fe Mossbauer spectroscopy in chemistry and biology, magnetochemical methods and models, cryoadiolysis as a method for mechanistic studies, absolute chiral structures of inorganic compounds, the
flash photolysis and chemistry of transients and excited states, using high pressure to elucidate inorganic and bioinorganic reaction mechanisms, chemical kinetics as a mechanistic tool, heavy atom isotope effects as probes of small molecule activation, and computational studies of reactivity in transition metal chemistry.
However, laser
flash photolysis does show that a reaction is occuring on the order of 3.5 X [10 sup 9][L.mol sup -1].[sup -1] (2) Fither energy transfer occurs despite thermodynamics or an electron transfer occurs.
These short-lived intermediates are observed using laser
flash photolysis, (5) a technique that allows observation of species living as low as a few femtoseconds and helps determine reactions' rate constants.
In the present research, DE was dissolved in water using the inclusion effect of CD, after which we examined its resonant two-photon ionization TPI [3] by laser
flash photolysis (LFP), where the sample was irradiated with light at a wavelength of 266 nm.
She continues to work under the direction of Scaiano on pesticide photodecomposition and the properties of the resulting radicals using laser
flash photolysis techniques.
