MAC it happen : Presented is a study of the synergistic structuredirecting effect of metal–amine complexes (MACs) with different chelating polyamine ligands and imidazolium-based ionic liquid (IL) cations. For the first time, a layered selenidostannate with an asymmetric eight-membered ring, an organic-decorated layered selenidostannate, and a 3D selenidostannate with both the MAC and IL cation...

Infrared photodissociation spectroscopy

The infrared photodissociation spectra of [(CO2)n(H2O)m] (n = 1–4, m = 1, 2) are measured in the 3000–3800 cm range. The [(CO2)n(H2O)1] spectra are characterized by a sharp band around 3570 cm except for n = 1; [(CO2)1(H2O)1] does not photodissociate in the spectral range studied. The [(CO2)n(H2O)2] (n = 1, 2) species have similar spectral features with a broad band at ≈3340 cm. A drastic chang...

Ion core structure in (N2O)n(+) (n = 2-8) studied by infrared photodissociation spectroscopy.

IR photodissociation (IRPD) spectra of (N(2)O)(2)(+) x Ar and (N(2)O)(n)(+) with n=3-8 are measured in the 1000-2300 cm(-1) region. The (N(2)O)(2)(+) x Ar ion shows an IRPD band at 1154 cm(-1), which can be assigned to the out-of-phase combination of the nu(1) vibrations of the N(2)O components in the N(4)O(2)(+) ion; the positive charge is delocalized over the two N(2)O molecules. The geometry...

Infrared Photodissociation Spectroscopy of Cluster Anions in the Gas Phase

Opsin structure probed by raman spectroscopy of photoreceptor membranes.

The first nonresonance Raman spectra of photoreceptor membranes are presented. Information about the membrane protein, opsin, and the membrane phospholipids can be deduced. Opsin appears to contain alpha-helical structure but little beta structure. The tyrosine residues are predominantly hydrogen bonded, and disulfide bonds, if they are present, are not in the normal gauche-gauche configuration.
