Article Snippet: Donor−bridge−acceptor (D−B−A) systems in which a 3,5dimethyl-4-(9-anthracenyl)julolidine (DMJ-An) chromophore and a naphthalene-1,8:4,5-bis(dicarboximide) (NI) acceptor are linked by oligomeric 2,7fluorenone (FNn) bridges (n = 1−3) have been synthesized.. Selective photoexcitation of DMJ-An quantitatively produces DMJ+•-An−•, and An−• acts as a high-potential electron donor.. Femtosecond transient absorption spectroscopy in the visible and mid-IR regions showed that electron transfer occurs quantitatively in the sequence: DMJ-An−FNn−NI → DMJ-An−FNn−NI → DMJ-An−FNn−NI. Article Title: Water Dynamics in Cytoplasm-Like Crowded Environment Correlates with the Conformational Transition of the Macromolecular Crowder. Article Snippet: Polyethylene glycol (PEG) is a unique polymer material with enormous applicability in many industrial and scientific fields.. Here, its use as macromolecular crowder to mimic the cellular environment in vitro is the focus of the present study.. We show that femtosecond mid-IR pump-probe spectroscopy using three different IR probes, HDO, HN3 and azido-derivatized crowder, provides complete and stereoscopic information on water structure and dynamics in the cytoplasm-like macromolecular crowding environment. Article Title: Direct simulations of anharmonic infrared spectra using quantum mechanical/effective fragment potential molecular dynamics (QM/EFP-MD): methanol in water. Article Snippet: One of the most stringent tests for chemical accuracy of a hybrid quantum mechanical/molecular mechanical (QM/MM) molecular dynamics simulation method would be to directly compare the calculated vibrational spectra with the corresponding experimental results.. Here, the applicability of hybrid QM/effective fragment potential (EFP) to the simulations of methanol infrared spectra is investigated in detail.. It is demonstrated that the QM/EFP simulations in combination with time correlation function theory yield not only the fundamental transition bands but also the major overtone and combination bands of methanol dissolved in water in both midand near-IR regions. Article Title: Micro-Raman spectroscopic analysis of liquid-liquid phase separation. Article Snippet: The focus of our study was to gain insight into the molecular mechanism responsible for liquid–liquid phase separation (LLPS) in heterogeneous protein systems.. We utilized micro-Raman spectroscopy to analyze the conformational changes of proteins and the hydrogen-bond structure of water during LLPS.. Our findings suggest that micro-Raman spectroscopy is an effective tool for examining protein conformational changes within droplets. Article Title: Ultrafast Events of Photoexcited Iron(III) Chloride for Activation of Benzylic C-H Bonds. Article Snippet: The sample was kept inside a Harrick cell with two KBr windows (2 mm thickness and 1-inch diameter) separated by a 0.6 mm Article Title: Dynamics of Deep Eutectic Mixtures of Tetraethylammonium Halides/Ethylene Glycol Investigated with Ultrafast Infrared Spectroscopy. Article Snippet: Health and environmental risks posed by volatile organic solvents create an incentive to develop safer, less volatile solvents with the appropriate functionality.. Deep eutectic solvents and other low-volatility organic mixtures offer a highly tunable alternative through a mixture composition selection.. However, a significant gap exists in understanding the relationship between molecular-level properties and the resulting solvation and transport properties. Article Title: Rotational dynamics of thiocyanate ions in highly concentrated aqueous solutions. Article Snippet: The thiocyanate (SCN ) anion is known as one of the best denaturants, which is also capable of breaking the hydrogen-bond network of water and destabilizing native structures of proteins.. Despite prolonged efforts to understand the underlying mechanism of such Hofmeister effects, detailed dynamics of the ions in a highly concentrated solution have not been fully elucidated yet.. Here, we used a dispersive IR pump–probe spectroscopic method to study the dependence of vibrational lifetimes and rotational relaxation times of thiocyanate ions on KSCN concentration in D2O. Transmission Assay:Article Title: Study of the denaturation/aggregation behaviour of whole porcine plasma and its protein fractions during heating under acidic pH by variable-temperature FTIR spectroscopy Article Snippet: Variable-temperature (VT) Fourier transform infrared (FTIR) spectroscopy was employed to examine changes in secondary structure of whole plasma proteins as well as of plasma protein fractions (serum, serum albumin and globulins) upon heating at pH 4.5 and to establish their kinetics of thermally induced protein aggregation through formation of non-native intermolecular beta-sheets.. A detailed analysis of the amide I0 band in the VT-FTIR spectra indicated that plasma proteins were more thermally sensitive at pH 4.5 than at pH 7.5 both when found as mixtures and in monomolecular systems, with the thermal aggregation being strongly enhanced under acidic conditions, particularly in the case of serum albumin.. Comparison of the spectral changes of plasma and serum (fibrinogen-depleted plasma) during heating indicated that fibrinogen has no role in protein aggregation under acidic conditions, in contrast to findings at pH 7.5. |
