There are two peaks in NMR spectra below 90 mK. It is concluded that the higher-frequency peak corresponds to the signal from antiferromagnetically ordered planes and the lower-frequency peak from paramagnetic planes.doi:10.1016/S0921-4526(02)02025-2Keiichiro...
The following deconvolution settings were applied: Peak threshold: 2; Minimum peak height: 2; Bins per scan: 10; Deconvolution width: 8 scans; No baseline adjustment; Minimum 1 peaks per spectrum; No minimum required base peak intensity. MIDs for the following fragments were calculated. ...
Peak areas were normalized to cell volume in case of in vitro experiments, or to wet weight (mg) tissue. 13C enrichment in purine one carbon units (P1C) To calculate the 13C enrichment in the two 1C units of purines (ATP, ADP, AMP, GTP, GDP, GMP) from [13C]-formate, the ...
(Bruker AVANCE 300) nuclear magnetic resonance spectrometer. Chemical shifts for1H NMR and13C NMR spectra are given with respect to external (CH3)4Si (1H and13C). [D6] DMSO was used as a locking solvent unless otherwise stated. IR spectra were recorded using KBr pellets with an FT-IR ...

In the polyol method, commercial Pd/C powder was heat-treated via microwave irradiation at approximately 200 °C with the Ag precursor. X-ray diffraction (XRD) patterns of the as-synthesized powders (Supplementary Fig. 2) showed a clear peak shift compared to that of Pd/C due to ...
Barriers to Rotation in Methyl Formate by Dynamic NMR Spectroscopy and Barriers to 1,3 Oxygen-to...Studies the exchange broadening of the [sup 13]C peak for the E isomer of methyl formate ester at lower temperatures. Nuclear magnetic resonance spectroscopy for the E-to-Z and Z-to-E ...
The liquid products were collected at the conclusion of each electrocatalysis, and first identified to only contain formate by NMR (Aligent DD2–600), and then quantitatively analyzed using an ion chromatograph (Dionex ICS-600). The concentration of formate was determined from its IC peak area ...
found in the Au/SiO2-Schiff sample, for which a distinctive resonance peak with a carbon chemical shift atδ = 164 ppm was detected, which was in good agreement with the calculated NMR shift of the imine group (Fig.1c). The corresponding stretching vibration of this functional group...
ESDIAD normal emission reaches a peak in intensity in the temperature region where the molecular plane of the formate is believed to be perpendicular to the surface plane.doi:10.1016/0039-6028(93)90575-5M.B. JensenU. MylerP.A. Thiel
