Characteristic infrared frequencies of rotational isomers of alkyl chlorides
(Elsevier, 1962)
A study of the infrared spectra of primary, secondary and tertiary alkyl chlorides reveals that the frequency of the so-called C-Cl stretching mode is a function of the detailed structure in the vicinity of the C-Cl bond. ...
Inversion-vibration and inversion-rotation interactions in the ammonia molecule
(Elsevier, 1962)
An attempt has been made to extend the theory of ammonia inversion in order to account for the dependence of the inversion splitting on the full set of vibrational and rotational quantum numbers. The potential energy of ...
Identification of acid mucopolysaccharides by paper chromatography
(Elsevier, 1964)
A multiple solvent paper chromatography system is described which tentatively identifies most of the known mammalian acid mucopolysaccharides, when these are examined singly. Certain mucopolysaccharides may be identified ...
The production of a linear density gradient by means of a propertioning pump
(Elsevier, 1965-04)
Vibration-rotation energies of tetrahedral XY4 molecules : Part II. The fundamental [nu]3 of CH4
(Elsevier, 1961)
The matrix elements derived in the first paper of this series are used to compute the frequencies of the tetrahedral fine structure components of the rotational lines of the fundamental [nu]3 of CH4. The theoretically ...
Chemical synthesis of p-nitrophenyl [beta]-sophoroside and p-nitrophenyl [beta]-laminarabioside
(Elsevier, 1969-10)
Condensation of tetra-O-acetyl-[alpha]--glucopyranosyl bromide with p-nitrophenyl 4,6-O-benzylidene-[beta]--glucopyranoside followed by appropriate deblocking reactions gives rise to an approximately equimolar mixture of ...
