Identification of the D(3h) isomer of carbon trioxide (CO3) and its implications for atmospheric chemistry.
The CO3 molecule is considered an important reaction intermediate in the atmospheres of Earth and Mars for quenching electronically excited oxygen atoms and in contributing to the anomalous 18O isotope enrichment. The geometry of the CO3 intermediate plays an important role in explaining these effects; however, only the cyclic (C(2v)) isomer has been experimentally confirmed so far. Here, we re...
متن کاملComplete hexose isomer identification with mass spectrometry.
The first analytical method is presented for the identification and absolute configuration determination of all 24 aldohexose and 2-ketohexose isomers, including the D and L enantiomers for allose, altrose, galactose, glucose, gulose, idose, mannose, talose, fructose, psicose, sorbose, and tagatose. Two unique fixed ligand kinetic method combinations were discovered to create significant enough...
متن کاملIsomer identification and resolution in small gold clusters.
A variety of experimental techniques are used to resolve energetically close isomers of Au(7)(-) and Au(8)(-) by combining photoelectron spectroscopy and ab initio calculations. Two structurally distinct isomers are confirmed to exist in the cluster beam for both clusters. Populations of the different isomers in the cluster beam are tuned using Ar-tagging, O(2)-titration, and isoelectronic atom...

متن کاملIdentification of Risk Factors for Abnormal Postoperative Chemistry Labs after Primary Shoulder Arthroplasty
Purpose Purpose The purpose of this study was to determine patient-specific risk factors and clinical intervention rates for abnormal postoperative Chem-7 panels in shoulder arthroplasty patients. Methods Retrospectively, all primary anatomic total (aTSA) and reverse shoulder (RTSA) arthroplasties (between 2007-2013) performed at a single institution were identified. All patients underwent ro...
