In some cases this allows us to correct for erroneous assignments of the experimentally observed satellite peaks to the different shells around the impurity. 展开 关键词: Korringa-Kohn-Rostoker- hyperfine fields magnetization hyperfine satellite
In a variety of materials it is observed that some STMAS peaks are very broad compared with the corresponding MQMAS peaks, sometimes so broad that they are unobservable. We present 17O ( I=5/2) NMR spectra of two materials, chondrodite (2Mg 2SiO 4路 Mg(OH) 2) and clinohumite (4...
The Data Extractor utility program detected peaks, assigned precursor charges where possible (for those not successfully determined, 2+ to 5+ were considered), filtered MS/MS spectra by quality (spectra with peak number >4 and sequence tag length >2 were kept for MS/MS search), centroided ...
On the other hand, power spectra of satellite-derived SST exhibit strong peaks at both Mf and MSf frequencies, especially inside the Pearl River estuary. This indicates the importance of tidal mixing processes in the region with a near-fortnightly signal (Mf) associated with the nonlinear ...
Among the peaks, four peaks were identified and quantified by HPLC using analytical standards (the same materials as described in Section 2.5), whereas one peak (casuarinin) was identified by nuclear magnetic resonance (NMR) analysis (described in Section 2.7) and quantified by HPLC using ...
It can be seen that both BeiDou 2 (BDS2) and BeiDou 3 (BDS3) systems show two anomaly peaks in PAS on the geomagnetic storm day compared to the reference day, corresponding to 15:00 UT and 22:00 UT, indicating that the geomagnetic storm has a significant impact on the satellite ...
For this reason, the information about rainfall spikes and peaks, essential in hydrological applications to solve water balance, is not given in the raw measurements. This is particularly critical, especially in very small catchment areas, such as urban ones, which are vulnerable from the ...
