Detection of E-cyanomethanimine (HCN-dimer) towards Sagittarius B2(N) from the GBT PRIMOS Survey

March 20, 2013
Author(s)
Francis J. Lovas, Daniel P. Zaleski, Nathan A. Seifert, Amanda L. Steber, Matt T. Muckle, Ryan A. Loomis, Joanna F. Corby, Oscar Martinez, Kyle Crabtree, Phillip R. Jewell, Jan M. Hollis, David Vasquez, Jolie Nyiramahirwe, Nicole Sciortino, Kennedy Johnson, Michael C. McCarthy, Anthony J. Remijan, Brooks H. Pate
An understanding of the formation, distribution and overall excitation of large molecules in astronomical environments remains in question even though more than 170 distinct chemical compounds have been detected in astronomical environments. Furthermore, a

FACTORS INFLUENCING EXPOSURE TO ORGANOHALOGEN CONTAMINANTS IN PREDATORY BIRDS FROM COASTAL SOUTH CAROLINA, USA

March 15, 2013
Author(s)
Jessica L. Reiner, Jennifer Yordy, Sam Rossman, Peggy H. Ostrom, Stacy Hughes, Keely Bargnesi, James D. Elliot
Predatory bird species occupy high trophic levels and consequently are susceptible to bioaccumulating high levels of environmental contaminants. To evaluate potential risks from exposure to past- and current- use contaminants, levels of legacy contaminants

Quantitative measurements of glutathione in yeast cell lysate using 1H NMR

February 20, 2013
Author(s)
Steve Y. Rhieu, Aaron A. Urbas, Katrice Lippa, Vytas Reipa
A method for quantifying the level of glutathione (GSH) in yeast cell lysate is described using 1H NMR analysis. For quantification purposes, the 1H resonances corresponding to the Cys βCH2 of GSH were identified as having the fewest overlapping spectral

Fast standard addition method for LA-ICPMS using a spinning platform

February 19, 2013
Author(s)
John L. Molloy, Stephen E. Long, Fanny Claverie, Julian Malherbe, Naomi Bier
A method has been developed for the fast and easy determination of Pb, Sr, Ba, Ni, Cu, and Zn, which are of geological and environmental interest, in solid samples by Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICPMS) using a sample

The Detection of Interstellar Ethanimine (CH3CHNH) from Observations taken during the GBT PRIMOS Survey

February 13, 2013
Author(s)
Francis J. Lovas, Ryan A. Loomis, Daniel P. Zaleski, Amanda L. Steber, Justin L. Neill, Matthew T. Muckle, Brent J. Harris, Jan M. Hollis, Phillip R. Jewell, Valerio Lattanzi, Oscar Martines, Michael C. McCarthy, Anthony J. Remijan, Brooks H. Pate
As the availab¬¬ility of publicly accessible spectral line surveys from radio astronomy increases, new approaches to the identification of molecules in the interstellar medium are possible. We have performed reaction product screening measurements using

Metallofullerene with a Distorted Shape: Structural Investigation of Y3N@C78

January 24, 2013
Author(s)
Dan Bearden, Jianyuan Zhang, Fuhrer Tim, Wujun Fu, Tianming Zuo, Liaosa Xu, Harry C. Dorn
In recent decades, the trimetallic nitride template endohedral metallofullerenes (TNT-EMFs),1 which consist of a trimetallic nitride cluster and a fullerene cage, have attracted extensive research interest due to their unique structural characteristics and

Spatial and temporal trends of persistent organic pollutants and mercury in beluga whales (Delphinapterus leucas) from Alaska

January 24, 2013
Author(s)
Jennifer Hoguet, Jessica Reiner, Jennifer Lynch, John Kucklick, Colleen E. Bryan Sallee, Amanda Moors, Rebecca Pugh, Paul R. Becker
Remote locations, such as the Arctic, are often sinks for persistent contaminants which can ultimately bioaccumulate in local wildlife. Assessing temporal contaminant trends in the Arctic is important in understanding whether restrictions on legacy

To Predict Vibrational Spectra, Are Anharmonic Calculations Worthwhile?

January 22, 2013
Author(s)
Ruth L. Jacobsen, Karl K. Irikura, Russell D. Johnson III, Raghu N. Kacker
Anharmonic calculations using vibrational perturbation theory are known to provide near-spectroscopic accuracy when combined with high-level ab initio potential energy functions. However, performance with economical, popular electronic structure methods is
