One-Alpha Descriptor [PDF]

open access: yesIranian journal of mathemathical chemistry, 2018
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 valueα. We show that these analyses may be on interest, because even good predictions of
