Single and multi-regression analysis
Opis:: Single and multi-regression analysis was applied for the corrosion study of transmission of substituent effects on IR carbonyl stretching frequencies and 13C chemical shifts of some substituted oxazepin compounds. The substituent effects were estimated on the basis of results of the statistical analysis. The differences among the obtained regression coefficients were discussed in terms of the relative importance of the field, inductive and resonance effects of substituent.

Opis:: Some 2’-hydroxyphenylchalcones have been synthesized under microwave irradiation by Claisen-Schmidt condensation between substituted 2-hydroxyacetophenone and substituted benzaldehydes using catalytic amount of SiO2-H3PO4. These chalcones were established by their physical constants and spectroscopic data published earlier. The UV, IR, 1H NMR and 13C NMR spectral data of these chalcone have correlated with Hammett substituent constants, F and R parameters. All the compounds have been subjected to screened for antimicrobial activity.
