Linear and nonlinear spectroscopic techniques applied to study of transient molecular species [PDF]

open access: yes, 2011
Carbon chain radicals and ions have long been known to exist in the interstellar medium, and considered as potential carriers for diffuse interstellar bands.

Asymmetric Monomethine Cyanine Dyes with Hydrophobic Functionalities for Fluorescent Intercalator Displacement Assay

open access: yesMolecules, 2023
A new green procedure has been applied for the synthesis and purification of asymmetric monomethine cyanine dyes. The photophysical properties of the newly synthesized compounds have been examined by combined application of spectroscopic and theoretical ...

Investigations on spectroscopic parameters and molecular constants of SO+ (b4∑-) cation

open access: yesActa Physica Sinica, 2012
The potential energy curve (PEC) of b4Σ- electronic state of the SO+ cation is calculated using the internally contracted multireference configuration interaction approach with the Davidson modification (MRCI+Q) for internuclear separations from 0.103 to 1.083 nm. The basis set used is a correlation- consistent aug-cc-pV5Z basis set.

Spectroscopic constants from atomic properties: a machine learning approach [PDF]

open access: yes, 2023
We present a machine-learning approach toward predicting spectroscopic constants based on atomic properties. After collecting spectroscopic information on diatomics and generating an extensive database, we employ Gaussian process regression to identify ...

Understanding exciton diffusion in organic solar cells [PDF]

open access: yes, 2013
Organic solar cells are promising candidates for future energy production. However, many challenges remain to optimise efficiency. One particular challenge lies in our understanding of the factors affecting exciton diffusion and the length scale of this

A High-resolution Spectroscopic Analysis of Aminoacrylonitrile and an Interstellar Search toward G+0.693

open access: yesThe Astrophysical Journal, 2023
Cyanides, ranging from three carbon atoms to polycyclic aromatic hydrocarbons, and alkenyl compounds are abundant in the interstellar medium. Aminoacrylonitrile (3-Amino-2-propenenitrile, H _2 N–CH=CH–C≡N), an alkenyl cyanide, thus represents a promising

Interaction of anticancer reduced Schiff base coumarin derivatives with human serum albumin investigated by fluorescence quenching and molecular modeling [PDF]

open access: yes, 2014
The specific binding of five reduced Schiff base derived 7-amino-coumarin compounds with antitumor activity to human serum albumin, the principal binding protein of blood, was studied by fluorescence spectroscopy.

Binuclear copper(II) complexes: Synthesis, structural characterization, DNA binding and in silico studies [PDF]

open access: yesJournal of the Serbian Chemical Society, 2020
Two new binuclear Cu(II) complexes represented by the general formula {(dmso)Cu(μ-L)4Cu(dmso)} (1) and {(Phen)(L)Cu(μ-L)2Cu(L)(Phen)} (2) where dmso = dimethyl sulphoxide, L = 2-bromophenyl acetate and Phen = = 1,10-phenanthroline have been synthesized ...

Rate constants for the reaction of NO and HO2 with peroxy radicals formed from the reaction of OH, Cl or NO3 with alkenes, dienes and α,β-unsaturated carbonyls [PDF]

open access: yes, 2003
Rate constants for the gas-phase reaction of NO and HO2 radicals with 33 peroxy radicals are presented. The peroxy radicals are derived from the addition of either OH, Cl, or NO3 radicals, followed by addition of O2, to a series of alkenes ...

A millifluidic calorimeter with InfraRed thermography for the measurement of chemical reaction enthalpy and kinetics [PDF]

open access: yes, 2008
The aim of this work is to present an infrared calorimeter for the measurement of the kinetics and the enthalpy of high exothermic chemical reactions. The main idea is to use a millifluidic chip where the channel acts as a chemical reactor.
