DESIGN OF A QSRR: E INDEX WITH HIGH MOLECULAR INFORMATION CONTENT TO DIFFERENCIATE CIS AND TRANS ALQUENES
Using QSRR modelling, an E index was designed based on the H. P. Schultz MTI index. The E index is a molecular descriptor consisting of a vector and adjacent and distant matrices. Linear regressions were obtained by means of a QSRR - GLC study of a set of 11 cis and 11 trans alquenes characterized b...
