Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Spectroscopic Constants of the Di-Atom PN [PDF]

open access: yesNature, 1935
IN a recent paper1, I ventured to predict that (a) “the internuclear distance of PN may be taken as closely approximating to the mean of the experimental values for NN and PP” (p. 28), and that (b) “it may be expected that experiment may show that PN has the highest bond constant and mean restoring force in the LK and KL periods” (p. 36).

Ab Initio study of spectroscopic constant and anharmonic force field of OCN2

open access: yes四川大学学报. 自然科学版, 2017
we calculate the equilibrium geometry structure of OCN2 by using B3LYP, B3p86, B3pw91 and MP2 methods combining  with cc-pVnZ (n=D,T) and aug-cc-pwCVDZ basis sets.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Molecular Interaction Between Cationic Polymer Polyethyleneimine and Rose Bengal Dye: A Spectroscopic Study

open access: yesJournal of the Turkish Chemical Society, Section A: Chemistry, 2019
The binding mechanism and polymer–fluorescence probe interactions between polyethyleneimine (PEI) and Rose Bengal (RB) was investigated by using UV–Vis absorption, steady- state and time-resolved fluorescence spectroscopy techniques since they remain ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

An Intruder-Free Fock Space Coupled-Cluster Study of the Potential Energy Curves of LiMg+ within the (2,0) Sector

open access: yesMolecules
The potential energy curves (PECs) and spectroscopic constants of the ground and excited states of a LiMg+ molecular cation were investigated. We obtained accurate results for the fifteen lowest-lying states of the LiMg+ cation using the Intermediate ...

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...
