| Abstract | ||
| This research is concerned with studying the vibration frequencies of the (C=N and O-H) groups in eight of Schiff bases using the HF method as one of the ab initio methods of quantum mechanics. The gas phase is compared with the situation of dissolving with the presence of the solvent such as methanol and tetrachloride carbon to find out the features and energy variables that result from the structural variables for the (8) bases and the various temperature , The results showed value by HF method in addition to agreement between the experimental values and the calculated chemical behavior of these rules . The relations among each variables has been evaluated .The extent and nature of the effect and impact of each variables upon the others is estimated by the values of correlation coefficient and standard deviation. The result of the simple and multi parametric correlation analysis showed good consistency between the experimental and Theoretical results . | ||
