In order to perform the analysis of the components contained in fossil fuels, carbon assignments of new methylated derivatives of tetralin and indan were obtained. Their chemical shifts were calculated by applying additivity rules.

Carbon-13 chemical shift data have been acquired for 36 methylated tetralins and tetrahydroanthracenes. A least-squares regression analysis has been undertaken on the ring carbons of compounds of unequivocal conformation to determine methyl substituent parameters for the two distinct aliphatic positions and the results have been used to estimate the position of equilibrium of conformationally mobile
