Accurate mass measurements confirmed the empirical formulae for the significant ions in the EI spectra and the mono-halogenated butanol structures. Further CI experiments with other reagent gases and instruments revealed possible molecular weights of 139 and 183Da, respectively. Tandem mass spectrometry ...
An isostructural pseudopolymorph of 9-deoxo-9a-aza-9a-methyl-9a-homoerythromycin A of formula (I) is new and has the monoclinic space group, average unit cell parameters as given in the specification. [Image] S 1an organic solvent which is at least partially miscible with water; x : 1,...
11(b), the quantitative analysis of cross-selectivity was calculated using the formula K = SC2H6O/So, where K represents the selectivity coefficient, SC3H6O denotes the sensor response, and So signifies the response of the C2H6O, C6H6, CH4, and NO2. The ratios of response of SC3H6O /S...
The percentage inhibition of inflammation was intended to be consistent with the following formula: % inhibition = 100 (1 − Vt/Vc), where ‘Vc’ stands for the inflammation volume in the control and ‘Vt’ for the inflammation volume in the group treated with tested drugs. 2.4.4. ...
Two additional Cu-TOAs with the general formula [Ti5O6Cu4(OOCR)16] were reported by Artner and co-workers [89] from reaction between [Ti(iOPr)4] and Cu(CH3COO)2 with either methacrylic acid (MA) or propionic acid (PA), in a Ti:Cu ratios 1:2 and 1:1 for MA and PA, ...
The occupancy factors of Al sites were constrained to a total number of Al atoms of 21.333 and 10.667 in the unit cell of the cubic and tetragonal models, respectively, accounting for the overall chemical formula of alumina. For each model the scale factor and lattice parameters, and thermal ...
wherein S2 is a chain of atoms of the formula: ##STR43## wherein h, i, k, m, p, and q may be independently be from 0 to 3; j and n may independently be 0 or 1; if j and n are both 1 and l is 0, then the sum of (k+m) must be at least 1; if n is 1 ...
for hemicellulosicmoiety, and had a specific band maximum inthe 1200-1000 cm-1region. This region is dominated by ring vibrations (C-Cstretching) and the glycosidic bond vibrations (C-O-C).The prominent band at 1043cm-1is attributed to the C-O stretchingin C-O-C glycosidic bonds. The ...
