Quantitative structure-retention relationship (QSRR) models for the gas chromatographic (GC) Kavats indices of disulfides on four different polarity stationary phase have been developed. Semi-empirical quantum chemical method (AM1) implemented in hyperchem 4.0 was employed to calculate a set of molecular descriptors of 50 disulfides. The four stationary phases in the research were: Apiezon M, OV-17,...
A study of the relationships between the extrapolated capacity factor (logk w ) of a group of 54 disubstituted benzene derivatives and a set of eight molecular descriptors was made. By using multiple linear regression (MLR), we obtained an empirical function, which included five descriptors. The performance of a radial basis function neural network (RBFNN) was evaluated. The network used thin...
A quantitative structure-retention relationship (QSRR) model has been developed for the gas chromatographic Kovats indices of 98 saturated esters on seven different polar stationary phases by multiple linear regression analysis (MLR). The seven stationary phases are: SE-30, OV-7, DC-710, OV-25, 100% phenyl, DC-230 and DC-530. Chemical descriptors were calculated from the molecular structures by PM3...
