We analyze the possibility of a ferroelectric transition in heteronuclear molecules consisting of Bose-Bose, Bose-Fermi, or Fermi-Fermi atom pairs. This transition is characterized by the appearance of a spontaneous electric polarization below a critical temperature. We discuss the existence of a ferroelectric Fermi liquid phase for Fermi molecules and the existence of a ferroelectric superflui...

Heteronuclear NMR in combination with isotope labelling is used to study folding of polypeptides induced by metals the case metallothioneins, binding peptidic allosteric modulator ?-TIA human G-protein coupled ?1b adrenergic receptor, development therapeutic drugs that interfere biosynthesis outer membrane Gram-negative bacteria, and a system which protein assembly upon peptide addition. these ...

The paper describes the multiple rotating frame technique for designing modulated rf fields, that perform broadband heteronuclear decoupling in solution NMR spectroscopy. The decoupling method presented here is understood by performing a sequence of coordinate transformations, each of which demodulates a component of the rf field to a static component, that progressively averages the chemical s...

Xanthones and benzothiazoles are important classes of heterocyclic compounds with versatile biological activities. Herein, we describe a straightforward scalable synthesis 5-chloro-6-oxo-6H-xantheno[4,3-d]thiazole-2-carbonitrile, thiazole-fused xanthone, via six-step approach, using Appel’s salt for the thiazole ring. The xanthone was fully characterized employing 1H 13C NMR spectra, direct lon...

The development of ▶ single-molecule spectroscopy has allowed for the investigation of a variety of biological questions previously inaccessible by ensemble techniques. The strength of single-molecule tools comes from the high-resolution data extracted from such experiments. Proper interpretation of these data requires efficient, unbiased analysis routines that are able to distinguish relevant ...
