[Report] Experimental ground-state combination differences of CH5+

20-Mar-2015 | Oskar Asvany; Koichi M. T. Yamada; Sandra Brünken; Alexey Potapov; Stephan Schlemmer, Science , 2015

Protonation of methane (CH4), a rather rigid molecule well described by quantum mechanics, produces CH5+, a prototypical floppy molecule that has eluded definitive spectroscopic description. Experimental measurement of high-resolution spectra of pure CH5+ samples poses a formidable challenge. By ...

Controlled Tautomeric Switching in Azonaphthols Tuned by Substituents on the Phenyl Ring

08-Dec-2014 | Liudmil Antonov, Vera Deneva, Svilen Simeonov, Vanya Kurteva, Aurelien Crochet, Katharina M. Fromm, Boris Shivachev, ..., ChemPhysChem, 2014

Abstract A series of new tautomeric azonaphthols are synthesized and the possibilities for molecular switching are investigated using molecular spectroscopy, X‐ray analysis and density functional theory quantum chemical calculations. Two opposite effects that influence switching are studied: ...

Self-Association of Amphotericin B: Spontaneous Formation of Molecular Structures Responsible for the Toxic Side Effects of the Antibiotic

21-Nov-2014 | Joanna Starzyk; Marcin Gruszecki; Krzysztof Tutaj; Rafal Luchowski; Radoslaw Szlazak; Piotr Wasko; Wojciech Grudzins ..., Journal of Physical Chemistry B, 2014

Amphotericin B (AmB) is a lifesaving antibiotic used to treat deep-seated mycotic infections. Both the pharmaceutical activity and highly toxic side effects of the drug rely on its interaction with biomembranes, which is governed by the molecular organization of AmB. In the present work, we ...

Competitive Interactions of Ionic Surfactants with Salbutamol and Bovine Serum Albumin: A Molecular Spectroscopy Study with Implications for Salbutamol in Food Analysis

05-Aug-2013 | Qiulan Zhang; Yongnian Ni; Serge Kokot, Journal of Agricultural and Food Chemistry, 2013

The effect of ionic surfactants, sodium dodecyl sulfate (SDS) and N-cetyl-N,N,N-trimethylammonium bromide (CTAB), on the interaction between β-agonist salbutamol (SAL) and bovine serum albumin (BSA) was investigated with the use of fluorescence spectroscopy (FLS) and chemometrics methods ...

Application Potential of ATR-FT/IR Molecular Spectroscopy in Animal Nutrition: Revelation of Protein Molecular Structures of Canola Meal and Presscake, As Affected by Heat-Processing Methods, in Relationship with Their Protein Digestive Behavior and Utilization for Dairy Cattle

30-May-2013 | Katerina Theodoridou; Peiqiang Yu, Journal of Agricultural and Food Chemistry, 2013

Protein quality relies not only on total protein but also on protein inherent structures. The most commonly occurring protein secondary structures (α-helix and β-sheet) may influence protein quality, nutrient utilization, and digestive behavior. The objectives of this study were to reveal the ...

Identifying Single Molecular Ions by Resolved Sideband Measurements

22-Apr-2013 | James E. Goeders; Craig R. Clark; Grahame Vittorini; Kenneth Wright; C. Ricardo Viteri; Kenneth R. Brown, Journal of Physical Chemistry A, 2013

The masses of single molecular ions are nondestructively measured by cotrapping the ion of interest with a laser-cooled atomic ion, 40Ca+. Measurement of the resolved sidebands of a dipole forbidden transition on the atomic ion reveals the normal-mode frequencies of the two ion system. The mass ...

Molecular spectroscopy and dynamics: A polyad-based perspective.

17-Apr-2013 | Michel Herman; David S Perry, Physical Chemistry Chemical Physics, 2013

The efficiency and insight of global, polyad-based modeling in overtone spectroscopy and dynamics is demonstrated. Both vibration and vibration-rotation polyads are considered. The spectroscopic implications of polyad Hamiltonians derive from their ability to account for the detailed line ...

SERS Detection of Small Inorganic Molecules and Ions

16-Oct-2012 | Ramón A. Alvarez‐Puebla, Luis M. Liz‐Marzán, Angewandte Chemie International Edition, 2012

Abstract Surface‐enhanced Raman scattering (SERS) is one of the most straightforward applications of the so‐called nanoplasmonics. This powerful molecular spectroscopy technique is based on the enhancement of the inelastic scattering from molecules located near nanostructured metallic surfaces ...
