The temperature derivatives of the above properties may be obtained by adding .Dtemperature to the property name, e.g. vaporPressure.Dtemperature

temperature
Double; temperature (K) at which to retrieve the property values

Returns:

value
Double; values for the temperature dependent properties. Return value is a row vector with one element for each compound.
