摘要:

A new method is described for the assay of Trimipramine maleate, the hydrogen maleate of 5-(3-dimethyl amino-2-methyl-propyl)-10,11-dihydrodibenz-[b,f]-azepine and its base using pmr technique. The method employed is precise, accurate, rapid and helpful in qualitative identification and purity of the drug.

摘要:

An accurate, more convenient and less time-consuming PMR procedure is described for the quantitative determination of cineole in bulk drug and in a sample of eucalyptus oil. Standard mixtures containing pure cineole showed a mean result of 100.6 ± 0.7%. The results, obtained by applying this method for the determination of cineole in eucalyptus oil, are compared with those found using the official BP method.

摘要:

ESR study of the brown - modification of some copper (II) - aroylhydrazone complexes revealed a reduction in the type of polycrystalline spectra which have been noticed for the corresponding green - form complexes. The estimated values of both magnetic susceptibility and magnetic moment were less than those for the green chelates.

摘要:

The IR spectra of SiH2I2was recorded in the gaseous, liquid and solid phases, in the range 4000-250 cm−1. An assignment of the observed bands is proposed and the measured frequencies are compared with the existing data for the other members of the series SiH2X2(X: halogen).

摘要:

The infrared and Raman spectra oftrans-Ni(S2N2CH3)2and Pd(S3N)2were measured from 4000-200 cm−1. The absorption bands were assigned by comparison to the sulfur nitride complexes of nickel(II), palladium(II) and platinum(II). Normal coordinate analyses on these complexes were carried on these data using molecular parameters taken from X-ray data. To aid in band assignments, isotope shift data ontrans-62Ni(S2N2CH3)2have also been carried out.

摘要:

Nuclear Magnetic Resonance (NMR) spectrometry has been used to characterize coal tar pitch oils, which had been obtained from a low-temperature carbonization of high volatile bituminous coal. NMR provides data on hydrogen distribution in coal oils and structural correlations established on elution chromatographic, on distillation fractions, and on the residues remaining after distillation. This research is the first report on the hydrogen distribution of coal tar pitch oils by NMR.
