Infrared and 13C NMR Spectral Correlation Analysis of Some Substituted Oxazepin Based Ketone and Thione Derivatives with Hammett Constant

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.
