Probe Beam Dichroism and Birefringence in Stumulated Raman Scattering of Biologically Relevant Polyatomic Molecules
Bogdan V. Semak, Yaroslav M. Beltukov, Oleg S. Vasyutinskii
The dichroism and birefringence effects in stumulated Raman scattering (SRS) in polyatomic molecules were studied theoretically. General expressions have been derived describing th…
Determination of quantum yield of NADH and FAD in alcohol-water solutions: the analysis of radiative and nonradiative relaxation pathways
Ioanna A. Gorbunova, Marina K. Danilova, Maxim E. Sasin +3
Combined studies on fluorescence quantum yield in coenzymes NADH and FAD in water-methanol, water-ethanol and water-propylene glycol mixtures and on time-resolved fluorescence of t…
Coherent Atomic Orbital Polarization Probes the Geometric Phase in Photodissociation of Polyatomic Molecules
Chaya Weeraratna, Arthur G. Suits, Oleg S. Vasyutinskii
Quantum interference between multiple pathways in molecular photodissociation often results in angular momentum polarization of atomic products and this can give deep insight into…
Two-Photon Excited Fluorescence Dynamics in NADH in water-methanol solutions: the Role of Conformational States
Ioanna A. Gorbunova, Maxim E. Sasin, Jesus Rubayo-Soneira +2
The dynamics of polarized fluorescence in NADH at 460 nm under two-photon excitation at 720 nm by femtosecond laser pulses in water-methanol solutions has been studied experimental…
Anisotropic relaxation in NADH excited states studied by polarization-modulation pump-probe transient spectroscopy
Ioanna A. Gorbunova, Maxim E. Sasin, Yaroslav M. Beltukov +2
We present the results of experimental and theoretical studies of fast anisotropic relaxation and rotational diffusion in the first electron excited state of biological coenzyme NA…
Ultrafast polarization-modulation transient spectroscopy to study electronic excited state dynamics in solutions and cells
Ioanna Gorbunova, Nikolay Bezverkhnii, Maxim Sasin +2
A novel polarization-modulation transient method has been developed for studying fast anisotropic relaxation in electronic excited states of polyatomic and biologically relevant mo…
