Matrix reactions of silicon difluoride as studied by infrared spectroscopy
Infrared matrix isolation spectroscopy has been employed to characterize monomeric silicon difluoride. Warm-up experiments show the development of several sets of new bands which indicate that this molecule polymerizes ...
Chemical syntheses in electric discharge
Several types of radio-frequency, induction-coupled plasma torches have been used for studying gaseous and gas-solid reactions at high temperatures. After a detailed examination of the various parameters which affect the ...
Rotational assignment and analysis of hyperfine structure of the microwave spectrum of chlorine dioxide
The microwave spectrum of chlorine dioxide has been studied and the frequencies of about 600 lines ranging from 8000 Mc to 55 000 Mc are tabulated. Several rotational transitions of C13502, C13702, and C1350 16018 have ...
The aglucone of sinigrin
The mechanism of the ascorbate-activated cleavage of sinigrin to mustard oil has been postulated as enzymatic hydrolysis of the thioglucoside to the aglucone, which undergoes spontaneous Lossen rearrangement to allyl ...
Phenolate radical coupling as a method of triterpene synthesis
The dienone [B] is a possible precursor for the synthesis of tetra- and pentacyclic triterpenes. In this investigation a synthesis of the dimeric phenol [A] and the conversion of [A] to [B] by a phenolate radical coupling ...
Assignment of microwave rotational spectra by computer
A computer program was written to assign the rotational quantum number transitions to the lines in a microwave spectrum. Lines in the spectrum of allyl alcohol were assigned using this program.
Ionization and dissociation studies of propadiene, 1, 3-butadiene, 1,3 trans-pentadiene, 2,4-hexadiene and 2,5-dimethyl-2,4-hexadiene by electron impact
The ionization and dissociation of propadiene, 1,3-butadiene, 1,3-trans-pentadiene, 2,4-hexadiene and 2,5-dimethy1-2,4-hexadiene have been studied using a CEC-21-701 mass spectrometer. The ionization potentials measured ...
