Two novel molecular structure descriptors based on distance matrix and adjacency matrix, named C N and C T were proposed which characterized branch vertex and molecular structural size of polycyclic aromatic hydrocarbons (PAHs), respectively. A quantitative structure-retention relationship (QSRR) model for estimating gas chromatography retention indexes of 100 polycyclic aromatic hydrocarbons was constructed by multiple linear regression (MLR). A satisfactory results were obtained that the correlation coefficients in partial least square and cross validation using leave-one-out (LOO) were 0.99...
