The molecular geometry and vibrational frequencies of 4,4'-bipyridine (BPE) in the ground state were calculated using density functional theory (DFT) methods (B3LYP) with 6-31++G(d,p) basis set. The optimized geometric bond lengths and bond angles are obtained by DFT employing the
A novel screening experiment, to find radioactive probes for non-invasive measurements of physiological functions in experimental animals, was tested using the in vivo multitracer analysis technique. The details of the efficiency of the detector settings used in the in vivo

Nitrate-delta(15)N from groundwater samples is determined on an inorganic nitrate derivative using automated, continuous-flow elemental analyzer/isotope ratio mass spectrometry (EA/IRMS). Nitrate is extracted and concentrated based on a recently published ion-exchange resin method. Freeze-dried AgNO(3) (0.5-1.5 mg) is packed in
