Summary The possible relation existing between RF values obtained by thin-layer chromatography for a group of anilines with connectivity indices proposed by Kier and Hall has been studied. Using multivariable regression the corresponding connectivity functions, selected for their respective correlation coefficients, standard deviations, Snedecor's F and Student's t were obtained. Regression analysis of the connectivity functions gives a correct prediction of the experimental elution sequence for this group of substances on silica gel stationary phases and various mobile phases of different polarity. The corresponding random and stability studies of the different prediction models selected were carried out, showing good stability and null randomness in all cases. 相似文献

Background
Spt7 is an integral component of the multi-subunit SAGA complex that is required for the expression of ~10% of yeast genes. Two forms of Spt7 have been identified, the second of which is truncated at its C-terminus and found in the SAGA-like (SLIK) complex. 相似文献3.

Summary A study has been made of the relationship between the RF values obtained by thin layer chromatography for a group of barbiturates and the connectivity indices proposed by Kier and
Hall. By using multivariable regression we obtained the corresponding connectivity functions, which were selected on the basis
of their respective statistics parameters. The regression analysis of the connectivity functions shows a correct prediction
of the experimental elution sequence for this group of molecules on silicagel with two mobile phases of different polarity.
The corresponding random and stability studies of the different prediction models selected were carried out, demonstrating
good stability and null randomness in all cases. The results also demonstrated that different structural features determine
the RF values in TLC of barbiturates. 相似文献

has been studied. Using multivariable regression the corresponding connectivity functions, selected for their respective correlation
coefficients, standard deviations, Snedecor’s F and Student’s t were obtained. Regression analysis of the connectivity functions
gives a correct prediction of the experimental elution sequence for this group of substances on silica gel stationary phases
and various mobile phases of different polarity. The corresponding random and stability studies of the different prediction
models selected were carried out, showing good stability and null randomness in all cases. 相似文献
