The molecular mass of the enzyme was 115 kDa and its molecule was composed of three molecules of subunits with the same molecular mass of 40 kDa. The enzyme contained 3 atoms of nonheme iron in the molecule and was active when the iron atoms were in a ferrous state. The enzyme consumed...
Given that the molecular mass of a compound is 360 g/mol, and that it has an empirical formula of CH2O, what is its' molecular formula? What is the empirical formula of benzene? The molecular formula mass of the compound CH2O is 120 amu. What are the subscripts in the actual molecular...
For structure elucidation of these natural diterpenoids intensive one- and two-dimensional NMR techniques (1H, 13C, APT, DEPT, NOE/NOESY, 1H–1H COSY, HETCOR, COLOC, HMQC/HSQC, HMBC, SINEPT) were used besides mass and some other spectroscopic methods. select article Raman microscopy as a ...
The thermal conversion of N2O on Rh(111) single-crystal surfaces has been studied using a collimated effusive molecular beam technique coupled with mass spectroscopy detection. The decomposition of pure N2O was determined to occur at temperatures as low as 120 K, to follow first-order kinetics, ...
N2O is subsequently stripped from the vial, cryofocused (Sansone et al., 1997) and introduced into the carrier stream of a Finnigan MAT252 mass spectrometer through an online gas chromatographic front end. N2O is thereby separated from residual CO2 and its d15N value determined from masses 44...
The molecules of compound1 exist in the crystal as dual ions. The molecules of compound2 are compact and their external chain is twisted in a characteristic way (similar to that found in peptides). 展开 关键词: INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRY PLASMA STABILITY ACOUSTIC NOISE AUDIO-...
