LIX.—The relation between the absorption spectra of acids and their salts. Part I. Sodium salts

Infra-red Absorption Spectra of Pyrylium Salts

The infra-red absorption spectra of the unsubstituted pyrylium cation and of 25 di-, tri-, tetraand per&-substituted pyrylium salts (mostly perchlorates) with alkyl and/or phenyl groups are described. Assignments of IR bands are made in correlation with the spectrum of pyridine, and the variation of band position and intensity depending on substitution is discussed. Implications for the assignm...

Complex Salts of Amino Acids and Peptides I. Metal Complex Salts of Glycine and Their Specificity by Max Bergmann

The mixtures of amino acids resulting from the hydrolysis of proteins and similar substances may be analyzed by the well known methods of Kossel and Kutscher, Fischer, Dakin, Van Slyke, Osborne, Vickery, and others. However, after hydrolyzing proteins with enzymes, one is faced with the difficult problem of determining the resultant amino acids and peptides without t,he occurrence of secondary ...

Effects of some salts and acids on citrus leaf abscission

the relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test

the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...

Relation of Iron Salts

I t has been previously reported (1) that brains of mice infected with the Theiler FA strain of mouse encephalomyelitis virus show marked inhibition in the rate of glucose phosphorylation. Since such impairment in the utilization of the most essential substrate of brain metabolism may be related to the neuron destruction in the course of the virus infection, its mechanism was investigated furth...
