Particle-particle and quasiparticle random phase approximations: Connections to coupled cluster theory [PDF]
, 2013 We establish a formal connection between the particle-particle (pp) random phase approximation (RPA) and the ladder channel of the coupled cluster doubles (CCD) equations.

An air-stable bisboron complex: a practical bidentate Lewis acid catalyst
Beilstein Journal of Organic Chemistry, 2018 We report an air-stable bisboron complex as an efficient catalyst for the inverse electron-demand Diels–Alder (IEDDA) reaction of 1,2-diazine as well as 1,2,4,5-tetrazine.

Atmospheric chemistry of gas-phase polycyclic aromatic hydrocarbons: formation of atmospheric mutagens. [PDF]
, 1994 The atmospheric chemistry of the 2- to 4-ring polycyclic aromatic hydrocarbons (PAH), which exist mainly in the gas phase in the atmosphere, is discussed. The dominant loss process for the gas-phase PAH is by reaction with the hydroxyl radical, resulting

NeoPHOX – a structurally tunable ligand system for asymmetric catalysis
Beilstein Journal of Organic Chemistry, 2016 A synthesis of new NeoPHOX ligands derived from serine or threonine has been developed. The central intermediate is a NeoPHOX derivative bearing a methoxycarbonyl group at the stereogenic center next to the oxazoline N atom.

Widespread HCO emission in the M82's nuclear starburst [PDF]
, 2002 We present a high-resolution (~ 5'') image of the nucleus of M82 showing the presence of widespread emission of the formyl radical (HCO). The HCO map, the first obtained in an external galaxy, reveals the existence of a structured disk of ~ 650 pc full ...

Classical Trajectories for two Ring-Shaped Potentials
, 1998 This paper deals with the classical trajectories for two super-integrable systems: a system known in quantum chemistry as the Hartmann system and a system of potential use in quantum chemistry and nuclear physics.

On the prevalence of bridged macrocyclic pyrroloindolines formed in regiodivergent alkylations of tryptophan. [PDF]
, 2016 A Friedel-Crafts alkylation is described that efficiently transforms tryptophan-containing peptides into macrocycles of varying ring connectivity. Factors are surveyed that influence the distribution of regioisomers, with a focus on indole C3-alkylations
