One-Alpha Descriptor

Recently, one-two descriptor has been defined and it has been shown that it is a good predictor of the heat capacity at p constant (cp) and of the total surface area (tsa). in this paper, we analyze its generalizations by replacing the value 2 by arbitrary positive value α. we show that these analyses may be on interest, because even good predictions of cp and tsa can be slightly improved. furthermore, it can be expected that this more general descriptor can find a wider range of application than the original one. the extremal values of trees have been found for all values of α.
