We report the first photoinduced single-crystal-to-single-crystal (SCSC) phase transition of a gold complex that involves the shortening of intermolecular aurophilic bonds. This is also the first solid state photochromism of a gold complex. Upon UV irradiation, the blue-emitting crystals of the gold(i) isocyanide complex 1 (1B) transform into the weakly yellow-emitting polymorph 1Y. X-ray diffr...

Protein-DNA binding assays have been used in a variety of applications from fundamental studies regarding the binding process itself to serve as probes for the detection, quantification and separation of target analytes. Here we describe a novel method of analyzing and identifying intermolecular DNA interactions that allows for the simple separation of interacting nucleoprotein complex componen...

NMR structures of protein-protein and protein-ligand complexes rely heavily on intermolecular NOEs. Recent work has shown that if no significant conformational changes occur upon complex formation residual dipolar coupling can replace most of the NOE restraints in protein-protein complexes, while restraints derived from chemical shift perturbations can largely replace intermolecular NOEs in pro...

the second virial coefficients are given as a spherical-core contribution plus a series of nonspherical perturbation terms. a revised analysis is given of the effect of long-range nonspherical terms in the intermolecular potential on the second virial coefficient given by a preferred hfdidl spherical core treatment of the integration for small intermolecular distances. this effect is considered...

The rotational spectrum of the van der Waals complex CH4-CO has been measured with the intracavity OROTRON jet spectrometer in the frequency range of 110-145 GHz. Newly observed and assigned transitions belong to the K = 2-1 subband correlating with the rotationless jCH4 = 0 ground state and the K = 2-1 and K = 0-1 subbands correlating with the jCH4 = 2 excited state of free methane. The (appro...

Rotationally resolved infrared spectra of the ν1 and ν3 N-H stretching vibrations of the Ar-NH2 radical ionic complex have been observed by means of photodissociation spectroscopy. The analysis of the rotational structure shows that the complex has a 3Σground electronic state with a linear or quasi-linear proton-bound structure Ar-H-N-H+ characterized by an intermolecular center of mass separat...

A revised analysis of the effect of long-range nonspherical terms in the intermolecular potential on the second virial coefficient is presented with a preferred Hartree-Fock-Dispersion functional (HFD-C) spherical core treatment of the integrations for small intermolecular distances. A set of modified numerical tables for the accurate calculation of the nonspherical contribution to the sec...

Many intermolecular chemical interactions persist across length and timescales and can be considered to form a "network" or "graph." Obvious examples include the hydrogen bond networks formed by polar solvents such as water or alcohols. In fact, there are many similarities between intermolecular chemical networks like those formed by hydrogen bonding and the complex and distributed networks fou...

The second virial coefficients are given as a spherical-core contribution plus a series of nonspherical perturbation terms. A revised analysis is given of the effect of long-range nonspherical terms in the intermolecular potential on the second virial coefficient given by a preferred HFDIDl spherical core treatment of the integration for small intermolecular distances. This effect is consid...

The syntheses of isoroquefortine C and a related heterocycle were achieved by implementation of both intra- and intermolecular vinyl amidation reactions. These accomplishments represent a significant advance in the use of these strategies in the generation of complex molecules.
