IR spectra of 0.3 m aqueous solutions of Mgo.5K3_ nHw ATP were plotted. The dependence of the spectra on the hydrolysis was investigated for three different K/H ratios of the nonhydrolysed system. Changes to bands provide information as to the protons added to the phosphate groups and base residues as a function of the initial protonation and degree of hydrolysis. More and more proton addition ...
An abundance analysis for the carbon-enhanced, extremely iron-poor (1⁄2Fe=H 3:5) star CS 29498-043 has been obtained using new high-resolution, high signal-to-noise ratio spectra from the Subaru Telescope. The [O i] forbidden line at 6300 8 and the O i triplet feature at 7771–7776 8 are both clearly detected. The overabundance of oxygen is significant (1⁄2O=Fe > 2). In addition, Na, Co, and Ni ...
