The importance of high density as a feature of potential fuel systems that seek to maximize net volumetric heat of combustion is well documented. The prediction of the crystal density of an unknown compound typically has been approached through the use of volume additivity procedures [29-32]. Here, the crystal-molecular volume ycm) is calculated by summing appropriate crystal-atomic or group volumes Vca Vcm = ca) and the corresponding crystal density is ob-...

There are still some workers who are unable to comprehend this point. It is nevertheless true that group volumes are not useful as steric parameters. They are actually... 

The character variables (i.e., the group volumes) are steric parameters of known utility in QSAR, but, despite the empirical success (i.e., eqs. 13 and 14), the steric meaning of locator variables is generally rather obscure.
