The infrared spectra (3500–50 cm−1) of the gas and solid and the Raman spectrum (3200–30 cm−1) of liquid germacyclopentane, c-C4H8GeH2, have been recorded. Additionally, the infrared spectra (3200–400 cm−1) of liquid xenon solutions have been recorded at −65 and −95 ...
The extent of double enchainment can be quantified by1H NMR spectrum to determine the unsaturation/divinylbenzene (TUS/DOU) ratio of the copolymer. Thus, for a linear copolymer of the Formula (I), without any double enchainment at the incorporated divinylbenzene units, a1H NMR spectra would...
In formula 1 above, R preferably represents a C1 to C10 aliphatic, alicyclic or aromatic hydrocarbon radical such as ethyl (Et), phenyl, isopropyl, butyl, propyl, n-butyl, i-butyl, t-butyl, hexyl, cyclohexyl, octyl, napthyl, etc. Non-limiting, illustrative examples of formula (1) and ...
(R′) OH where R and R′ are either alkyl or alicylic substituents, in which case the benzhydryl carbon is incorporated in a cyclopentane or cyclohexane ring for use in the preparation of glycidyl polyethers having the formula: where B is the divalent hydrocarbon radical of the bisphenol and...
General formulae of carboxamide (a), amidine (b), amidinate complexes (c), and amidinosilanes prepared in this work (d). Since about two decades the research of our group is concerned with different types of silicon-nitrogen compounds like silicon carbodiimides (Balan et al., 2000; Kim ...

What is the formula mass of a molecule of CO2? Draw the complete structural formula for each of the following compound. a. Butane b. 3-methylhexane c. 3-ethyl-4-methyldecane d. 4-methyl-2-heptene e. 5,6-dimethyl-4-octyne f. 1,3-diethylcyclopentane g. 1-methyl-3- propylbenzene ...
These recurring molecular moieties may correspond to the formula in which n is at least 4, preferably 4 to 6, and the substituent is hydrogen, an alkyl radical, a cycloalkyl radical or an alkoxy radical. Compounds containing, for example, one or more basic nitrogen atoms may be employed...
Predict the molecular structure for XeO_2F_2. Sketch the molecular structure of 2,4-dimethylhexane. Give the molecular formula for the following structure. Provide the molecular formula of the given condensed structure. Predict the molecular structure for BrFl_2. ...
Syntheses of novel prostaglandin (PG) mimetics without PG skeleton are described, and the structure-activity relationships are discussed. Highly potent compounds could be obtained when the PG analog 3 was modified by removing and reconstructing the cyclopentane ring, and changing the allylic alcohol in...
